Question

ferrous salts are more unstable than ferric salts.why?​

Answer 1

Answer:

The Fe3+ ion is more stable than Fe2+ because due to its electronic configuration i.e. the electronic configuration of Fe3+ has half - filled last orbital and we know that half or full filled orbitals are more stable and here Fe2+ has not half or full filled orbitals,so Fe3+ ion is more stable than Fe2+ ion.
