Anhydrous copper sulphate (white ) turns blue with water .

Calculate the enthalpy of hydration of anhydrous copper sulphate (CuSO_4) into hydrated copper sulphate (CuSO_4 cdot 5H_2O) . Given that the enthalpies of solution of anhydrous copper sulphate and hydrated copper sulphate are -66.5 and + 11.7 kJ mol^(-1) respectively.

When an aqueous solution of copper (II) sulphate is saturated with ammonia, the blue compound crystallises on evaporation. The formula of this blue compound is:

If a aqueous solution of copper (II) sulphate is saturated with ammoina, the blue compound ----- crystallises on evaporation.

Copper sulphate solution does not react with

Copper sulphate is soluble in water.

Why is copper sulphate pentahydrate coloured?

The solution in a beaker turns blue if

Why hydrated copper sulphate is blue while anhydrous copper sulphate is white?

Give reason for each of the following: Copper sulphate pentahydrate turns white when treated with concentrated sulphuric acid.

Give reason : The blue colour of aqueous copper sulphate fades when it is electrolysed using platinum electrodes.
