In the aqueous solution, Cu(+1) salts are unstable because

Options

A. Cu(+1) has a `3d^(10)` configuration
B. the change in free energy of the overall reaction is zero
C. they disproportionate easily to the Cu and Cu (+2) states
D. they disproportionate easily to the Cu (+2) and Cu (+3) states.

Answer

C

Explanation

`Cu^(+)` salts are unstable in aqueous solution since they disproportionate easly to Cu and `Cu^(2+)` state.
