i just know it is to acidify the solution but can you explain in detail
thanks

i know it is to acidfy the sulotion but i need detail explanation
also what is the purpose for heating the oxalic acid solution b4 titrating??

The (MnO4)- ion needs H+ ions in order to take away the O atoms to make water - look at the half-equation:
(MnO4)- + 8H+ + 5e- -------> Mn2+ + 4H2O
The reaction is heated in order to speed up the reaction, which is very slow at room temperature.

I guess the reaction that u r trying to do is oxidize oxalic acid ... in an oxidation/reduction rxn ...hmm ... i know that with the increase in acid, the solvation ability of the reaction will help make the reaction proceeds to the right faster... in addition, i think u need a catalyst for this reaction... but since there is no catalyst mentioned, i think that increasing acidity will drive the reaction to the RIGHT -- oxidation of oxalic acid based on Le- Chateler Principle..
