Standardisation of 0.02moldm-3 Potassium Permanganate Solution using Lab Report

Standardisation of 0.02moldm-3 Potassium Permanganate Solution using Ferrous ammonium ion Sulphate (Ammonium Iron (II) Sulphate) - Lab Report ExampleThe reaction between these two chemical moieties is a typical Redox reaction in which electron exchange takes place as depicted beneath9.8 grams of Ferrous Ammonium sulphate was carefully weighed and transferred to a volumetric flask. 150 milliliters of Sulphuric Acid was added to sustain hydrolysis and the mixture was stirred until the solid dissolved completely. The volume was made up to the mark with de-ionized water. 25 milliliters of the issue was removed from the flask with a pipette and titrated with the KMno4 solution until the first appearance of permanent pink colour. At the endpoint all of the Fe2+ has been used up (reacted) and the purple permanganate is no longer converted to colourless Mn+2 so the pink colour remains and the reaction solution will have a permanent pink tinge to it (Web, Undated). A second titration was performed to substantiate data for analysis and reduce kitchen range for error.The strength of the un cognize Potassium permanganate solution in this reaction is calculated by titrating it a known molar solution of Ferrous Ammonium sulphate which provides us with the molarity of the KMnO4 solution.This experiment proves that when molar piece of writing of one chemical composite is known, and we can have a physical end point in a redox reaction with visible colour change, we can standardize the strength of an unknown compound by using the technique of volumetric
