WebOct 4, 2024 · For example, it can be shown that aqueous potassium permanganate, KMnO 4, at its absorption maximum of 530 nm, has an extinction coefficient ε = 14 L g-1 cm-1. How much light is absorbed by a sample of potassium permanganate at that wavelength depends on a couple of additional factors, however. WebKMnO 4 act as a powerful oxidizing agent in acidic, neutral and alkaline medium. e.g. In acidic medium, KMnO 4 + H 2 SO 4 ——-> K 2 SO 4 + MnSO 4 + H 2 O + O In neutral medium, KMnO 4 + H 2 O ——-> KOH + MnO 2 + O In alkaline medium, KMnO 4 + KOH ——–> K 2 MnO 4 + H 2 O + O It oxidizes ferrous sulphate to ferric sulphate
