WebDetermination of strength of KMnO 4 using standard solution of Mohr's salt. In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent. Mohr’s salt is a double salt of ferrous sulphate and ammonium sulphate and its composition is FeSO 4 . (NH 4) 2 SO 4 .6H 2 O. WebProcedure: Take a watch glass, wash it with distilled water and dry it. Weigh the exact amount of clean and dried watch glass and record its weight in the notebook. Weigh correctly on the watch glass 3.15 g of oxalic acid and record this weight in the notebook. Using a funnel, transfer oxalic acid softly and carefully from the watch glass into ...
