Zn (Zinc) salts are white while `Cu^(2+)` salts are coloured. Comment on it.

Zn^(2+) salts are white while Cu^(2+) salts are blue, explain why ?

Zn salts are white, Ni^(++) salts are blue explain

Why Zn^(2+) salts are colourless and Ni2+ salts are coloured?

Why Cd^(2+) salts are white ? Cd=48

Ions of Zn^(2+) and Ti^(4+) are colourless while Cu^(2+) and Ni^(2+) are coloured . Why ?

PCl_5 reacts with finely divided silver on heating and a white silver salt is obtained, which dissolves on adding excess aqueous NH_3 solution. Write the reactions involved to explain what happens.

An inorganic salt (A) is decomposed on heating to give two products (B) and (C). Compound (C) is a liquid at room temperature and is neutral to litmus while the compound (B) is a colourless neutral gas. Compounds (A), (B) and (C) are

Out of Co^(2+) , Zn^(2+) and Cu^+(2+) which will give aqueous coloured solution ?
