Answer 2

Salts of Zn, Cd, and Hg are white because these elements do not contain unpaired electrons in their highest oxidation state.

Explanation:

It is known that, when elements do not have any unpaired electrons in their ground or highest oxidation state then compounds formed by then are colorless.

For example, atomic number of zinc is 30 and its electronic configuration is $[Ar]4s^{2}3d^{10}$. Highest oxidation state of zinc is +2 and then its electronic configuration becomes $[Ar]3d^{10}$.

So, there are no unpaired electrons due to which it will not form colored compounds.

Hence, salts of Zn, Cd and Hg are white.
