Given below are two statements:

Statement (I): A solution of

\left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}

is green in colour.

Statement (II): A solution of

\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}

is colourless.

In the light of the above statements, choose the most appropriate answer from the options given below:

View answer and explanation

Correct option: B

Both Statement I and Statement II are correct

Option B (Both Statement I and Statement II are correct) is correct because

\left[\mathrm{Ni}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}

is green due to d-d transitions, and

\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}

is colorless due to being diamagnetic.
