perchloric acid titration of amine oxalate salts
Hi guys ! I need some guidance on non-aqueous titration. I am trying to do a non-aq (HClO4) titration of an oxalate salt of a primary amine. It is not
directly titratable with perchloric acid. When I add hercuric acetate solution, there is heavy precipitation of mercuric oxalate so end point
detection is difficult even on potentiometer. Is there any alternative to mercuric acetate? Or any other alternative titration method for oxalate
salts of amines?

Why not do a simple aqueous titration of the oxalate with permanganate?
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Actually I want to assay the oxalate salt for the amine content. The amine would also be reactive with KMnO4.......

If you are doing this in acetic acid then I cannot fathom why you are adding mercuric acetate. Oxalic acid is such a weak acid in comparison to
perchloric that it should have little effect on the conductivity. In acetic acid solvent amines are strong bases and perchloric acid is a strong
acid.
