A 10.00-ml aliquot of unknown oxalic acid solution required 15.44ml of
0.01117M KMnO4 solution to reach the purple end point.A blank titration of
10ml of similar solution containing no oxalic acid required 0.04ml to
exhibit detectable color.Find the voncentration of oxalic acid in the unknown.
可否请会算的版友详列算式呢?
谢谢
