Dissolving and hydratation reaction (this gives the blue color of Cu hydrated ions)
CuSO4 + 4H2O --> Cu(H2O)42+ + SO42-
followed by two differend protolysis reactions, of which the first is relatively stronger acidic than the second (wich is very weakly basic):
- Cu(H2O)42+ + H2O ==> Cu(OH)(H2O)3+ + H3O+
- SO42- + H2O --> HSO4- + OH-

Why it is recommended to prepare ferrous ammonium sulfate solution in acidic medium?
It is recommended to prepare ferrous ammonium sulphate solution in acidic medium because iron when combined with water gives the precipitates of oxides of Iron.
Will a displacement reaction occur between copper and green sulphate solution?
What is the metal cation that gives the 'green' colour.
A substance with equal numbers of H and OH ions is an alkaline solution?
No, only exces of OH- gives you an alkaline solution and exces of H+ gives you an acidic solution. When they are EQUAL then the solution (water) is NEUTRAL, pH= 7.0
Which anions give a white precipitate with silver nitrate?
chloride and sulphate ions give white precipitate with silver ion in aqueous solution but sulphate gives slightly dirty white.
Which indicator gives us reddish pink color in acidic solution?
Methyl red and methyl orange show reddish colors in acidic solutions.

What is half saturation test of starch?
With 2ml of starch solution 2ml of saturated ammonium sulphate solution is added. Formation of gelatinous precipitate gives confirmation of presence of starch
