Consider the following transition metal ions. V 2+, Fe 2+, Zn 2+, T 4+, Mn 3+, Sc 3+ The number of ions that form colourless aqueous solution is. (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Zn 2+, Ti 4+ and Sc 3+ ions do not have unpaired d - electrons and hence, they form colourless aqueous solution.

Q. Consider the following transition metal ions.
$V^{2 +}, F e^{2 +}, Z n^{2 +}, T^{4 +}, M n^{3 +}, S c^{3 +}$
The number of ions that form colourless aqueous solution is______.

$Z n^{2 +}, T i^{4 +}$ and $S c^{3 +}$ ions do not have unpaired $d -$ electrons and hence, they form colourless aqueous solution.
