Question- Iron is often utilized to standardize permanganate solutions. A 0.158 g sample of pure iron wire was dissolved in dilute sulfuric acid to form a solution of iron (ii) sulfate. This was titrated with 31.23 ml of potassium permanganate solution. What was the molarity of the permanganate solution?

The above standardized permanganate solution was used to titrate the oxalic acid (H2C2O4) in rhubarb leaves. A 12.38 g sample of rhubarb leaves was extracted with water and the resulting oxalic acid solution was titrated with 36.56mL of the permanganate solution. What was the percent oxalic acid in the rhubarb?
