Transition Metals in Basic Copper Chloride

April 17, 2019 by shida wei  

A transition metal, Basic Copper Chloride(WSDTY) is the second to last member of the first-row transition metals. Transition metals typically have more than one common oxidation state: Basic Copper Chloride forms compounds with oxidation states+1(cuprous)and +2(cupric). Copper is a known exception to the Aufbau principle; copper would have the expected ground-state valence configuration of 4s23d9, but one electron is “borrowed” from the 4s orbital to completely fill the 3d orbitals, making the configuration 4s13d10. For the copper ions, the electron configuration of the cuprous ion (Cu+) is 4s03d10, while the configuration for the cupric ion (Cu2+) is 4s03d9. Cu+is stabilized in the solid phase, in which its compounds are generally colorless or white. The +2 state of copper dominates its aqueous chemistry, and it is more stable in that phase. Many Cu2+ compounds are blue due to the presence of the hexaaquacopper(II) ion, Cu(H2O)62+.

Basic Copper Chloride Exceeds Steady State Control

April 12, 2019 by shida wei  

The biochemical toxicity of Basic Copper Chloride(WSDTY), when it exceeds homeostatic control, is derived from its effects on the structure and function of biomolecules, such as DNA, membranes and proteins directly or through oxygen-radical mechanisms. The toxicity of a single oral dose of copper varies widely between species. The major soluble salts Basic Copper Chloride are generally more toxic than the less soluble salts. Death is preceded by gastric hemorrhage, tachycardia, hypotension, hemolytic crisis, convulsions and paralysis. Long-term exposure in rats and mice showed no overt signs of toxicity other than a dose-related reduction in growth after ingestion. The effects included inflammation of the liver and degeneration of kidney tubule epithelium. Some testicular degeneration and reduced neonatal body and organ weights were seen in rats ... and fetotoxic effects and malformations were seen at high dose levels. Neurochemical changes have been reported after oral administration A limited number of immunotoxicity studies showed humoral and cell-mediated immune function impairment in mice after oral intakes in drinking-water.

Aluminum and Basic Copper Chloride Lab: Limiting Reagent Edition

April 8, 2019 by shida wei  

It is important to note any physical characteristics of the reactants so that after the reaction, the experimenter can note any changes in color or properties. Those physical changes can be indicative of a chemical reaction. Basic Copper Chloride(WSDTY) has a distinctly blue hue, and once it is added to the water, the aqueous solution thus has a turquoise hue as well.

After the reaction has completed- usually this happens overnight. One must run the solution and the products through a filter. Filtration is a method for separating a mixture and very effective in separating solids from liquids. Then, one must let the filter paper, the precipitates and (potential) excess reactant dry out. After that, assuming that there is excess aluminum as their was in our reaction- one must separate the aluminum and the copper which is easy to using tweezers because they are very different colors and have different qualities.

Mass will always be measured in grams (or kg) in labs, which can be easily done using a gram scale. bThe amount of substance though will be measure in moles. Moles are indicated by coefficients in a balanced equation.

Synthesis of Basic Copper Chloride

April 1, 2019 by shida wei  

Basic Copper Chloride(WSDTY) is the chemical compound with the formula CuCl2. This is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate. The copper (II) chlorides are some of the most common copper (II) compounds, after copper sulfate.

Some simple stoichiometry can show us how much carbonate and acid to use and what out yield will be. In this experiment we will use 31.45% HCl since that is commonly found at many hardware stores. Since 36.46 g/mol is for pure 100% HCl we need to divide this by .3145. This yields 115.93 g/mol. Lets say I want 50 grams total of Copper (II) Chloride. I divide it's molar equation by 50 to get that ratio. 134.45/50 = 2.689. Now, I divide everything else by that ratio as well to keep the reaction balanced. Finally, since 1 mole of CuCO3 reacts with 2 moles of HCL, we need to multiply the HCl part by 2. This means that... 45.948 g + 86.225 g ---> 50 g + 16.3666 g + 6.699 g . This reaction actually forms H2CO3, or carbonic acid, but this quickly decomposes into CO2 and H2O so we don't really count it. This 50 grams of Copper Chloride is actually anhydrous, but when it combines with water, it forms a dihydrate, or CuCl2 . 2H2O. This means that the dried Copper Chloride will weigh more than 50 grams. It should weigh about 13.4 grams extra bringing it to a total of 63.4 grams. There may be some other complex copper chloride + water molecules in their as well, so it is hard to predict the true yield. That is what experimentation is for.

Crystalline Solid Basic Copper Chloride

March 27, 2019 by shida wei  

Here we have a Basic Copper Chloride(WSDTY), also known as copper oxychloride. This is not a mix of the two, but a crystalline solid, with copper, chlorine and oxygen in a single crystal lattice.

With this kind of compounds, the experimental outcome will be quite different when it is added to H2SO4. However, I certainly will try your suggestion and once I'm sure that I have pure anhydrous CuCl2 I'll do.

One big problem with investigating this compound is that it is so hard to isolate. Remember, it is in concentrated H2SO4. So, simply boiling off the liquid is out of the question (H2SO4 boils at appr. 300 degrees C and the fumes are insanely corrosive and lethal). Hot H2SO4 at 300 C eats everything in seconds. Filtering also is not an option with the viscous and very corrosive liquid. Conc. H2SO4 really is nasty stuff.

You are right with your conclusion that it could be copper chloride, anhydrous. I was fooled by the observation of the light yellow/brown stuff I made by boiling a solution of CuCl2 in HCl to dryness. The stuff I had made before is not pure anhydrous copper chloride, but it most likely was something with HCl incorporated in the solid.

Now, I've heated some of my reagent grade CuCl2.2H2O very slowly and carefully, taking care not to overheat it in order to avoid the making of basic copper chloride. The product I obtained is exactly the same as on the picture, but now as a dry powder. A nice dark brown and dry powder, which dissolves in water, giving a green solution, without any residue.

Producing Basic Copper Chloride

March 22, 2019 by shida wei  

If you're running a Basic Copper Chloride(WSDTY) mine, most of the ore you start with (the material you dig out of the ground) is anything but copper. Typically, copper ores contain only 4 percent copper, so the vast majority is waste. You can use a variety of different processes to separate the copper from the waste. The exact nature of the refining process depends on which metals and other materials the copper happens to be mixed with and how pure you need the final copper to be. The process usually takes several different stages. At each stage, more impurities are removed so the copper gradually becomes more concentrated and pure.

Typically, the process starts with ore being crushed into very small pieces and mixed with water to make a slurry. The slurry is pumped into tanks and mixed with air and oily chemicals that help to separate out particles of copper from the other minerals that may be present. The remaining ore is then heated in a huge furnace called a smelter, which burns off some of the remaining impurities and leaves a material called copper matte, which is at least 50 percent copper. A second heating process follows in which the copper matte is heated with silica and air to remove more waste, leaving a very refined material called blister copper that can be over 97 percent pure. An even purer form of copper can be made by a process called electrolysis, in which electricity is passed through a copper-containing solution. Copper made this way is 99.9 percent pure—and it needs to be, because even slight amounts of impurities reduce its ability to conduct electricity.

Overflow and Emergency of Basic Copper Chloride

March 13, 2019 by shida wei  

If Basic Copper Chloride(WSDTY) is spilled, take the following steps: Evacuate personnel and secure and control entrance to the area. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate and wash area after clean-up is complete. It may be necessary to contain and dispose of Copper Chloride as a HAZARDOUS WASTE. Contact your state Department of Environmental Protection (DEP) or your regional office of the federal Environmental Protection Agency (EPA) for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped.

Copper Chloride will react with STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE), and STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC) to produce toxic Hydrogen Chloride gas. Store in tightly closed containers in a cool, well-ventilated area away from MOISTURE and ALUMINUM.

Detection of Basic Copper Chloride

March 8, 2019 by shida wei  

If while wearing a filter or cartridge respirator you can smell, taste, or otherwise detect Basic Copper Chloride(WSDTY), or if while wearing particulate filters abnormal resistance to breathing is experienced, or eye irritation occurs while wearing a full facepiece respirator, leave the area immediately. Check to make sure the respirator-to face seal is still good. If it is, replace the filter or cartridge. If the seal is no longer good, you may need a new respirator.

NIOSH has established new testing and certification requirements for negative pressure, air purifying, particulate filter and filtering facepiece respirators. The filter classifications of dust/mist/fume, paint spray or pesticide prefilters, and filters for radon daughters, have been replaced with the N, R, and P series. Each series has three levels of filtering efficiency: 95%, 99%, and 99.9%. Check with your safety equipment supplier or your respirator manufacturer to determine which respirator is appropriate for your facility. Be sure to consider all potential exposures in your workplace. You may need a combination of filters, prefilters or cartridges to protect against different forms of a chemical (such as vapor and mist) or against a mixture of chemicals.

Basic Copper Chloride Control and Practice

March 4, 2019 by shida wei  

Unless Basic Copper Chloride(WSDTY) a less toxic chemical can be substituted for a hazardous substance, ENGINEERINGCONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary. In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible. In addition, the following control is recommended: Where possible, automatically transfer Copper Chloride from drums or other storage containers to process containers.

Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended: Workers whose clothing has been contaminated by Copper Chloride should change into clean clothing promptly. Do not take contaminated work clothes home. Family members could be exposed. Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to Copper Chloride. Eye wash fountains should be provided in the immediate work area for emergency use.
