of anhydrous copper sulfate (CuSO4) is white because it reflects lights in visible region of spectrum. Once water is added‚ it changes to blue as the structure of the copper transitional compound becomes Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. This compound absorbs light of wavelengths from 600 to 800nm (yellow-to-red region) light and blue light is transmitted. When ammonia is added to a solution of copper(II) cation‚

LAB REPORT FOR EXPERIMENT 3 COPPER CYCLE OLANREWAJU OYINDAMOLA TUESDAY 27TH February 2013 Abstract This experiment is based on copper‚ to synthesize some copper compound using Copper (II) nitrate solution to obtain copper metal at the end. Changes of copper complexes when various are added and filtering out the precipitate by using Buchner funnel for vacuum filtration .The experiment started with preparation of copper (II) hydroxide and addition of copper oxide then addition of droplets

One of the best and most common materials used to make heat sinks is copper. Copper has a very high thermal conductivity of 400 W/mK. It is‚ however‚ heavier than aluminum and more expensive. But for operating systems that require an extensive amount of

success. The most suitable material is going to be selected through comparisons among copper and aluminum alloys‚ which are commonly used in designing frying pan. This report is consisted of three parts. The first part is the introduction and objection. Second part is the findings and analyses through comparing two kinds of materials and the conclusion will be the last part. Objective People normally pick copper‚ cast iron‚ and aluminum alloys as the raw material for making a frying pan because

By measuring the mass of copper that forms‚ you will have the necessary information to determine the moles of copper and chlorine in your sample‚ and you will be able to establish the proper chemical formula. OBJECTIVES • • • In this experiment‚ you will Ev al Determine the water of hydration in a copper chloride hydrate sample. Conduct a reaction between a solution of copper chloride and solid aluminum.

illness develops from copper poisoning. Wilson’s Disease affects one in thirty thousand people world wide. The genetic defect causes excessive copper accumulation. Small amounts of copper are essential as vitamins. Copper is present in most foods‚ and most people get much more than they need. Healthy people excrete copper they don’t need‚ but Wilson’s Disease patients cannot. Copper begins to accumulate immediately after birth. Excess copper attacks the liver

we will study is called copper chloride hydrate. We first drive out the water‚ which is called hydration. This occurs if we gently heat the sample to a little over 100*C. The compound formed is anhydrous (no water) copper chloride. If we subtract its mass from that hydrate‚ we can determine the mass of the water that was driven off‚ and using the molar mass of water‚ find the number of moles of H2O that were in the sample. Next‚ we need to the find either the mass of copper of chlorine in the anhydrous
