∙ 11y agoanhydrous 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!!!!!!!!!!!

∙ 11y agoThe white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.
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.

copper sulphate
Fe = CuSO4 ----> FeSO4 + Cu
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
it changes colour from a white powder to a blue powder
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
No colour
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour

Nothing
It turns blue because copper forms blue crystals when in solution. As soon as the water evaporates, there's nowhere for the copper to be in "solution", so it loses its colour. When water is added again, the crystals regain the "solution" state and turn blue!
The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!
Sulphuric acid, because "sulphuric" is what gives copper sulphate it's name
