Question

Why freshly prepared solution of KMnO4 is boiled before using it in titration?

Answer 1

Answer:

What is the importance of boiling KMnO 4 solution if it is stored for future use? Because KMnO4 is a powerful oxidant, aqueous solution of it is not entirely stable because water can be oxidized. However, the decomposition reaction of water into O2 gas and MnO4- into MnO2 is relatively slow.
