RenePermanganate estimation is completed in acid because permanganate is a strong oxidizing agent and can decompose rapidly in alkaline solutions. When permanganate reacts in acidic conditions, it forms a stable product, manganese dioxide (MnO2). This reaction allows for accurate and reliable determination of the amount of permanganate present in the solution.

Why is permanganate estimation completed in acid solution?
Permanganate estimation is completed in acid solution because in acidic conditions, permanganate (MnO4-) is reduced to colorless manganous ion (Mn2+), allowing for the endpoint to be easily detected once all the substance being titrated has reacted. Additionally, the acid helps stabilize the permanganate solution and prevents premature oxidation.

In permanganate titration's why is nitric acid not used?
Nitric acid is not used in permanganate titrations because it can react with permanganate ions and reduce them before they can oxidize the analyte. This interference can lead to inaccurate results in the titration process. Instead, sulfuric acid is often used as the acidifying agent in permanganate titrations.
Why are titrations using permanganate performed in an acid solution?
Titrations using permanganate are performed in an acid solution to prevent the premature oxidation of permanganate. Acidic conditions stabilize permanganate in its purple form until it reacts with the analyte, ensuring accurate titration results.
Why potassium permanganate is used as a self indicator in the titration of oxalic acid?
Potassium permanganate is used as a self-indicator in the titration of oxalic acid because the initial pink color of potassium permanganate is decolorized in the presence of oxalic acid due to its reducing properties. The endpoint of the titration is reached when all the oxalic acid has reacted with the potassium permanganate, causing the pink color to persist. This change in color helps in determining the equivalence point of the titration.
