The brown precipitate is MnO2, it is the product of the following redox in neutral environment:

For each half reaction:

MnO4- + 4H++ 3e- → MnO2 + 2H2O REDUCTION

HSO3- + H2O → SO42- + 3H+ + 2e- OXIDATION

Overall: Permanaganate half reaction x2 + Bisulfite half reactionx3

2MnO4- + 3HSO3- + 8H+ + 3H2O + 6e- → 2MnO2 + 3SO42- + 4H2O + 9H+ + 6e-

Cancelling like terms:

2MnO4- + 3HSO3- → 2MnO2 + 3SO42- + H3O+

Note that all species are balanced, all charges are balanced and the brown precipitate MnO2 is accounted for. The reaction also predicts that acid is formed in the process.

What colour is the precipitate formed when sodium hydroxide reacts with potassium iodide?

They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...


Potassium permanganate is a deep purple solution so what happens when you add sodium hydroxide and pouring it on a large filter paper?

When potassium permanganate is mixed with sodium hydroxide, it forms a dark brown precipitate of manganese dioxide. When this mixture is poured onto a large filter paper, the precipitate will be retained on the paper while the liquid passes through, allowing for separation of the solid from the liquid.

What will happen if toluene react with potassium per magnate in presence of sodium carbonate?

When toluene reacts with potassium permanganate in the presence of sodium carbonate, the permanganate will oxidize the toluene to form benzoic acid. The sodium carbonate will help neutralize any acidic byproducts formed during the reaction.
