Does a change in color observed when copper II sulfate crystals become dehydrated how do you account for the change when water is added to the heated copper II sulfate?
Yes, copper (II) sulfate, also known as cupric sulfate, is a deep blue when it is hydrated (when it has water). If you heat it, the water evaporates and leaves plain copper (II) sulfate power, which is a cream color. So yes, dehydrating copper (II) sulfate in its hydrated form will cause it to change from blue to white. If you take this dehydrated (anhydrous) copper (II) sulfate and add water to it, it will become hydrated again, so the white powder will, once again, turn that deep blue color.
Why is anhydrous sodium sulfate added to organic solution remaining after the extraction with 6 M HCl and 6 M NaOH?
To get rid of excess water in the organic phase.
Why protein solution turns purple when copper sulfate solution is added?
Copper sulfate solution provides cupric ions that react with the peptide bonds present in the protein molecule. The test is called as biuret test, as it was originally given by biuret compound.( when urea is heated it forms biuret). The reaction is due to the formation of complex between the cupric ions and lone pair of electrons present on the Nitrogen and Oxygen atoms of peptide bond.
What happens when water is added to white copper sulfate?
Its sulphate not sulfate and sorry im not sure my self
Why does copper sulphate turn green when iron is added?
When iron is added to copper sulfate, the sulfate ionbreaks away from copper, and combines with iron to form Ferrous Sulfate, which is green in color. It is a single displacement reaction =CuSO4 + Fe ----> FeSO4 + Cu
What happens to magnesium when you mix aluminum and copper sulfate?
Please someone answer a question for CuSO4 + H2O+Al= What when added to Cupric Sulfate and Cupric Chloride? Need this for a science class!!
What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
When black copper oxide is added to dilute sulphuric acid what colour is the soloution at the end?
Blue cupric sulfate solutionAdded:Chemical formulas:- CuO, Cu(II)-oxide, cupric oxide (monocopper oxide), black- Cu2O, Cu(I)-oxide, cuprous oxide (dicopper oxide), red- sulfuric acid, H2SO4CuO + H2SO4 --> CuSO4 + H2O , cupric sulfate, blue solutionCu2O (red) also reacts with dilute sulfuric acid forming CuSO4 by:Cu2O + 2 H2SO4 --> CuSO4 + H2O + H2, cupric sulfate, blue solution

When Copper Sulphate is heated what is the observation?
When copper sulfate is heated the observation is that it turns white as the water which is driven off by the heat. It is also stated that the white solid will remain and if water is added to the anhydrous copper sulfate a reaction will occur.

What is the difference between anhydrous sodium thiosulphate and sodium thiosulphate?
None. Anhydrous simply means ..... (not in solution). The opposite is aqueous (in solution).Added:..... crystalised without hydrate in the solid crystals.mono-hydrate means it is crystallised with 1 (one) molecule H2O per molecule salt.CuSO4.5H2O means : penta-hydrate of copper sulfate
When copper sulfate is added to water it .......to form a?
Why does copper sulfate change its colour when water is added
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
If Clear dilute ammonia is added to blue copper sulfate solution does a chemical reaction happen?
