Permanganate 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.

What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
With potassium permanganate and sulfuric acid, a redox reaction occurs where potassium permanganate is reduced to manganese(II) ions and sulfuric acid is oxidized. With oxalic acid, potassium permanganate undergoes a redox reaction where it is reduced to manganese(II) ions and oxalic acid is oxidized to carbon dioxide and water.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
Which reaction produces more pure oxygen which is not united with other elements solid potassium permanganate with hydrogen peroxide or solid potassium permanganate with Sulfuric acid with H2O2?
The reaction that produces more pure oxygen which is not united with other elements is solid potassium permanganate with hydrogen peroxide rather than solid potassium permanganate with sulfuric acid with H2O2.
What is the equation of the reaction between oleic acid and potassium permanganate?
The equation for the reaction between oleic acid and potassium permanganate is not straightforward because it depends on the conditions and concentrations. Generally, potassium permanganate can oxidize oleic acid to form carbon dioxide and water along with other byproducts. The balanced equation will depend on the stoichiometry of the reaction and the specific conditions.
What is formed when potassium permagnet reacts with citric acid?
When potassium permanganate reacts with citric acid, manganese dioxide, water, and carbon dioxide are formed. The reaction is often used as a demonstration of the oxidative property of potassium permanganate and the reducing property of citric acid.
What is the titrimetric analysis of ethanol in fruit wines?
estimation of alcohol content in fruit wines can be done by titrating fruit wine against potassium permanganate.
Why is there colour change in the reaction between oxalic acid and potassium permanganate?
The color change in the reaction between oxalic acid and potassium permanganate is due to the reduction of purple potassium permanganate (MnO4-) to colorless manganese dioxide (MnO2). This reduction reaction causes the change in color from purple to colorless.
