Q. Assertion : $K_{2}[Ni(EDTA)]$ is more stable than $K_{3}[Al(C_{2}O_{ 4})_{3}]$.
Reason : Ni is a transition element while Al is a non transition element.

Coordination Compounds

Solution:

Greater stability of $K_{2}[Ni(EDTA)]$ is due to greater number of chelate (rings) formed by $EDTA$ as compared to $C_{2}O^{2-}_{4}$.
