Question

what happens when acidified KMnO4 if allowed to react with sodium oxalate

Answer 1

Redox reaction Occurs

Explanation:

When potassium permanganate is allowed to react with sodium oxalate oxidation-reduction happens. Potassium permanganate undergo reduction while sodium oxalate undergo oxidation. More specifically oxalate has a carbon atom which losses its outer electron and gets oxidized.

oxidation : It refers to the addition of oxygen and removal of electron and hydrogen

reduction : It refers to the addition of electron and hydrogen and removal of oxygen

Answer 2

kmno4 is a very strong oxidising agent whereas the so2 is strong reducing agent so the so2 reduces Mn. The equation for the reaction is 5so2+2kmno4+2h2o= 2h2so3+2mnso4+k2so4. KMNO4 is actually a very very strong oxidizing agent but SO2 is strong reducing agent so that SO2 reduces Mn♥️
