There is a redox reaction between oxalic acid being oxidised by acidic permanganate ions (MnO4-). Products are H2O(l) and CO2(g) and Mn2+ ions.

Why we ad sulpheric acid with oxalic acid?
we add sulpheric acid with oxalic acid to stable the ions when titrated against KMNO4
Can someone help with this chemical equation K4FeC6N6 plus KMnO4 plus H2SO4 KHSO4 plus Fe2S3?
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
Before reaction of kmno4 with oxalic acid why the reaction is slow and after reaction very fast why?

Ethyne when reacts with aqueous KMnO4 in cold condition forms formic acid and in hot condition oxalic acid it should not be reversed?
oh shut up yu@@%$#^%%@
Is potassium sulfate possible as a byproduct of manganese heptoxide synthesis?
Yes; the chemical reaction is:2 KMnO4 + 2 H2SO4 → Mn2O7 + H2O + 2 KHSO4
What is the oxidising agent in kmno4 h2c2o4 h2so4?
KMnO4 and H2SO4 are oxidising agents. Oxidising agents are hungry for electrons...
Why you add h2so4 to the kmno4 titration?
consider the balance chemical equation, suppose the reaction with oxalic acid 2MnO4- + 16H+ + 5C2O4 --> 2Mn+2 + 8H2O + 10CO2 Above reaction shows that the reaction requires a number of protons to occur, H2SO4 is the source of these protons.

Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.

What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
Potassium Permanganate (KMnO4) reacts with Sulphuric acid (H2SO4) to produce Manganese Heptoxide (MnO7), water (H20) and Potassium Hydrogen Sulphate (KHSO4)2. The reactive species produced is Manganese Heptoxide (which is a very powerful oxidiser). The Manganese Heptoxide will oxidise the Oxalic acid (COOH)2 to Carbon dioxide (CO2).
Why kmno4 is a secondary standard?
Potassium permanganate solutions due to the strong oxiding nature readily forms MnO2 on contact with impurities. Traditionally sources of KMnO4 always contained traces of MnO2 . KMnO4 solutions "go off" when they stand for a period.
What happens when zinc dust is added to an acidified solution of potassium permanganate?
KMno4 is reduced to Mn^2+ Salt and the pink colour is discharged by the nascent hydrogen produced when zinc reacts with h2so4
What is formed in the titration of FeCl2 with KMnO4 with H2SO4 present?
FeCl2 + 2KMnO4 --> Fe(MnO4)2 + 2KCl
What is Kno3 plus h2co3 k2co3 plus hno3?
The answer is: 4 KMnO4=2 K2O+4 MnO+5 O2
