K M n O 4 can be prepared from K 2 M n O 4 as per the reaction 3 M n O 4 2 - + 2 H 2 O ⇌ 2 M n O 4 - + M n O 2 + 4 O H - The reaction can go to completion by removing O H - ions by adding

Question

K M n O 4 can be prepared from K 2 M n O 4 as per the reaction 3 M n O 4 2 - + 2 H 2 O ⇌ 2 M n O 4 - + M n O 2 + 4 O H - The reaction can go to completion by removing O H - ions by adding, KOH, C O 2, S O 2, HCl

As M n O 4 - can oxidise S O 2 , HCl but not C O 2 as in C O 2 C-atom has its highest oxidation state (+4) it means C O 2 can be used here.
