Following are the transition metal ions ...

Following are the transition metal ions of 3d - series :
`Ti^(4+), V^(2+), Mn^(3+), Cr^(3+)` (Atomic no : Ti = 22, V = 23, Mn = 25, Cr = 24)
Answer the following :
Which ion is the stable in an aqueous solution and why ?

Text Solution

Verified by Experts

`Cr^(3+)`, due to stability of half - filled `t_(2g)^(3)` - orbital in aqueous solution.
