Estimation of Fe +2 by KMnO 4   as primary standard Oxalic acid Aim of experiment : Estimation of Fe2+ from supplied solution by standard KMnO4 Principle : This process was presented by Mabride in 1912. When oxalic acid acidified with dil.H2SO4 is titrated with potassium permanganate solution at 60-70 0 C temperature, an oxidation-reduction reaction takes place between these substances. The chemical reaction is When solution of Fe2+ ion acidified with dil. H2SO4 is titrated with potassium permanganate solution at room temperature, an oxidation-reduction reaction takes place between these substances. The chemical reaction is Required materials and solutions : Burette, pipette (20 ml), 250 ml conical flask, 250ml, volumetric flask, oxalic acid, potassium permanganate, etc. Part: I- Preparation of standard solution of oxalic acid Weigh accurately 1.125 g of oxalic acid in a chemical balance (or electronic balance) and transfer it to a 250 ml volumetric flask. Add 100 m
