Question

Which is reducing agent in redox titration of KMnO4 with oxalic acid

Answer 1

Answer:

Potassium Permanganate

• In this titration, the analyte is oxalic acid and the titrant is potassium permanganate.
• The oxalic acid acts as a reducing agent, and the KMnO4 acts as an oxidizing agent.

Answer 2

• The oxalic acid acts as a reducing agent, and the KMnO4 behaves as an oxidizing agent, KMnO4 behaves as a pointer where the permanganate ions are an intense purple colour. In this redox titration, MnO-4 is reduced to colourless manganous ions (Mn2+) in the acidic medium.
• KMnO4 is an oxidizing agent whose reactions occur in an acidic medium more strongly than in an alkaline medium. So, for quantitative calculation potassium permanganate is commonly borrowed in an acidic medium only.
• Initially, the purple-pink colour of potassium permanganate is released in reaction with oxalic acid. When a permanent pink colour arises, it demonstrates the endpoint.
