What is the role of KMnO4 during estimation of oxalic acid by titrating it with KMnO4?
Initially when we add potassium permanganate into conical flask containing oxalic acid, it gets discharged and the solution remain colourless. … Potassium permanganate reacts with sulphuric acid and forms manganous sulphate which works as catalyst for reduction of MnO4- .
What is the formula of oxalic acid?
The formula of oxalic acid is (C2H2O4); its usual form is that of the crystalline hydrate, (COOH)2·2H2O. Known as a constituent of wood sorrel as early as the 17th century, oxalic acid was first prepared synthetically in 1776.
What is the principle of volumetric analysis?
The basic principle of Volumetric analysis: The solution which we want to analyze contains a chemical of unknown amount then the reagent reacts with that chemical of unknown amount in the presence of an indicator to show the end-point. End-point shows that the reaction is complete.
How do you write a volumetric analysis?
Volumetric Analysis
- Prepare a solution from an accurately weighed sample to +/- 0.0001 g of the material to be analyzed.
- Choose a substance that will react rapidly and completely with the analyte and prepare a standard solution of this substance. …
- Place the standard solution in a buret and add it slowly to the unknown.
