2. The Mohr titration should be carried out under conditions of pH 6.5 – 9. At higher pH silver ions may be removed by precipitation with hydroxide ions, and at low pH chromate ions may be removed by an acid-base reaction to form hydrogen chromate ions or dichromate ions, affecting the accuracy of the end point. 3.

Result: The strength of the supplied unknown strength Mohr’s salt solution was …….g/L 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 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. Therefore, n-factor for mohr's salt will be 1 equivalent weight = molecular weight/ n- factor equivalent weight = molecular weight / 1 equivalent weight = molecular weight Regards. n factor of Mohr Salt is 4.
