50g of steel wire was dissolved in excessive of diluted sulphuric acid and the solution was made up to 250ml in a standard flask. 25ml of this solution was pipetted into a conical flask and needed 25.45ml of 0.02M KMnO4 for complete oxidation. calculate the percentage of iron in the sample.

What is the molarity of the acid sol'n?
  • JFraser
We don't need to know the concentration of the orignal acid, since the volume and concentration used in the oxidation tells us moles of iron anyway.
