Answer:

Most of the copper salts contain Cu2+ ion. ... Since it is evident from the electronic configuration Cu2+ io contain 1 unpaired electron which can undergo d-d transition. Thus Cu compounds are coloured. In case of Zn2+ there is no unpaired electron for the transitions thus Zinc compounds are colourless

hope it's helpful
