Strength = Normality x Equivalent weight = (1/20) x 392 = 19.6 g/L. For preparing 250ml of N/20 Mohr’s salt solution, Mohr salt required = (19.6/1000) x 250 = 4.9 gm Molar mass of Mohr’s salt is 392gmol-1. It is a primary standard. Since, 1000cm 3 of 1M potassium permanganate require Mohr’s salt of =392g So, 250cm 3 of M/20 potassium permanganate require Mohr’s salt of = \[\frac{\frac{392}{20}}{1000}\times 250\] = 4.9g. Accurately weigh 4.9g of Mohr’s salt using a chemical balance and watch glass 2. The Mohr titration should be carried out under conditions of pH 6.5 – 9.

Mohr's salt is - FeSO 4.(NH 4) 2 SO 4.6H 2 O. In Mohr's salt Fe is in +2 state (Fe 2 +) , it oxidises by removing 1 electron and converts to Fe 3 +. Mohr’s salt having the formula FeSO 4.(NH 4) 2 SO 4.6H 2 O has molar mass 392gmol-1. It is a primary standard. It’s equivalent mass is 392/1 = 392 as its n factor is 1 as per the following reaction: Fe 2+ → Fe 3+ + e – PROCEDURE: Weigh a clean dry bottle using a chemical balance. Mohr's salt is FeSO 4 (NH 4) 2 SO 4 . 6H 2 O On it's reaction with H 3 PO 4 Fe gets oxidised from Fe +2 to Fe +3.
