Question

potassium permangante reactwith hydrogen shulphide in acidic medium plz give me ans

Answer 1

In acid permanganate is reduced to Mn+2 and will oxidize hydrogen sulfide to sulfate SO4=.

MnO4- + 8 H3O+ 5e- = Mn++ + 12H2O

H2S + 14H2O = 2KMnO4 + 3H2S → 2MnO2 + 3S + 2KOH + 2H2O  

2KMnO4 + 3H2S → 2MnO2 + 3S + 2KOH + 2H2O
