Explain why `CuSO_4` is blue while `ZnSO_4` is colourless.

an aqueous solution of CuSO_4 is acidic while that of Na_2SO_4 is neutral. Explain.

Explain why 'NH3', is basic. while 'BiH3 is only feebly basic.

Hydrated copper sulphate, is blue while anhy drous copper sulphate is colourless, Why?

This energy lies in visible region and ie, why electronic transition t_(2g) hArr e_(g) are responsible for colour. Such transitions are not possible d^0 and d^10 configuration. Ti_((aq.))^(3+) is purple while Ti_((aq.))^(4+) is colourless because :
