A) gets oxidised by oxalic acid to chlorine
B) frunishes \[{{H}^{+}}\] ions in addition to those from oxalic acid
C) reduces permanganate to \[M{{n}^{2+}}\]
D) Oxidises oxalic acid to carbon dioxide and water
Correct Answer: C
Solution :
Titration of oxalic acid by \[KMn{{O}_{4}}\] in the presence of \[HCl\] gives unsatisfactory result because \[HCl\]is a better reducing agent than oxalic acid and \[HCl\]reduces preferably permanganate ion \[\left( MnO_{4}^{-} \right)\] to \[M{{n}^{2+}}\].You need to login to perform this action.
