Question

Cu from coloured salts while zn forms colourless salts explain

Answer 1

$\huge\underline\mathtt{Answer}$

Cu contains partially filled d orbitals in +2 oxidation state and thus, Cu2+ salts are coloured. However, Zn has completely filled d orbital which is highly stable, and hence, it does not form coloured ions. Hence, Cu forms coloured salts while Zn forms colourless salts.

Answer 2

Answer:-

Cu2+ salts are coloured, as they contain partially filled d orbitals in +2 oxidation state

However, Zn has completely filled d orbital which is highly stable than Cu, and hence, it does not form coloured ions.

Hence, Cu forms coloured salts while Zn forms colourless salts.
