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.
They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...
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.
Potassium permanganate and sulfite:2MnO4-(aq) + 5SO32-(aq) + 6H+(aq) --> 5SO42- + 2Mn2+(aq) + 3H2O(l)Note:Potassium and sodium ions do NOT react, they are tribune-ions
The name of the compound NaMnO4 is sodium permanganate.
The specific heat of sodium bisulfite is approximately 3.1 J/g°C.
Potassium permanganate and bisulfite in stronger acid environment:2MnO4-(aq) + 5HSO3-(aq) + H+(aq) --> 5SO42- + 2Mn2+(aq) + 3H2O(l)Note:Potassium and sodium ions do NOT react, they are tribune-ions.
Alkaline potassium permanganate solution is a solution of potassium permanganate containing an alkali. The alkali can be sodium hydroxide or potassium hydroxide.
KMnO4 is potassium permanganate.
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.

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.
