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 titration of potassium permanganate is carried out in acidic medium?
Potassium permanganate undergoes reduction in acidic medium which generates a color change that can be easily observed, making it suitable for use as an oxidizing agent in titrations. Additionally, the acidic medium prevents the premature reaction of permanganate ions with reducing agents present in the solution before the titration is conducted.
Why is permanganate estimation completed in acid?
it provides the H+ ions to catalyse the reaction
Is potassium permanganate is acidic or alkaline in nature?
Potassium permanganate is acidic in nature. When dissolved in water, it releases hydrogen ions which lower the pH of the solution, making it acidic.
What indicators used in redox titration?
Some common indicators used in redox titrations are potassium permanganate (KMnO4), which changes color from purple to colorless in acidic conditions, and potassium dichromate (K2Cr2O7), which changes from orange to green in acidic conditions. Other indicators include starch-iodine complex and ferroin.

Why phenolphthalein used in titration?
it acts as acid base indicator
What are correct regarding the reaction between potassium ferrocyanide and KMnO4 in acidic solution Permanganate ion is the oxidizing agent or Oxidized?
permanganate ion is an oxidising agent and is reduced.
How does acidic potassium permanganate react with ki?
Permanganate(purple) becomes Mn2+(pale pink) and Iodide becomes Iodine.
Why you use phenolphthalein in titration?
Phenolphthalein is used as an indicator in titrations because it changes color sharply at a specific pH range (approximately 8.2 to 10). This color change helps in determining the endpoint of the titration, which is when the reaction is complete. Phenolphthalein is colorless in acidic solutions and pink in basic solutions, making it ideal for acid-base titrations.
What is phenalphaline?
Phenolphthalein is a chemical compound commonly used as an acid-base indicator in titrations. It is colorless in acidic solutions and pink in basic solutions. It has also been used in the past as a laxative but is no longer commonly used for that purpose due to safety concerns.
Why toluene does not react with acidic or alkaline permanganates?
Toluene reacts with acidic permanganate on heating and forms the Benzoic acid.
