EXPERIMENT 1:
STANDARDIZATION OF KMNO4 USING SODIUM OXILATE
Oxalic acid (C.OH) is good reducing agent, which is usually used to
standardize KımnO, solution. However, the acid itself is rarely used direesl.
because it is difficult to be obtained in pure form and also it contains wate
crystallization. The sodium salt of the acid, sodium oxalate, is usually useA
because it is available in pure form and does not contain water of crystallizatiec
In strongly acidic solution under which the titration takes place, the oxalate
solution is equivalent to a solution of oxalic acid itself.

KMnO4 solution reacts with the oxalic according to the following equation:
