Determination of peroxydiphosphate in acid medium with oxalate (i) with silver(I) as catalyst and (ii) in the presence of excess of manganese(II).
Peroxydiphosphate can be determined with oxalate in acid medium in the presence of silver(I). Excess of oxalic acid along with the sample and silver (I) is heated to boiling and the excess of oxalic acid is titrated against standard permanganate. Another method involves boiling for 2 min a mixture consisting of the sample and excess of manganese(II), followed by titration of the resulting Mn(III) or MnO(2) with standard oxalic acid solution.
