to a green chromic salt when added to ferrous ammonium sulphate or Mohr’s salt [FeSO 4, (NH 4) 2 SO 4,6H 2 O] solution containing dilute H 2 SO 4. In this reaction ferrous sulphate is oxidized to ferric sulphate, while, ammonium sulphate remains unreacted. K 2 Cr 2 O 7 + 4 H 2 SO 4 → K 2 SO 4 + Cr 2 (SO 4) 3 + 4 H 2 O +3 [O] 6 FeSO 4 + 3 H 2 SO 4 + 3 [O]→ 3 Fe 2 (SO 4) 3

The iron in Mohr’s Salt is ferrous, and it certainly will be oxidised to ferric by the permanganate. The sulfate anion may also be oxidized to a free radical by electron transfer involving the manganese. This completed reaction would be described in the Inorganic Chemistry texts by Cotton and Wilkenson. 1.4K views Mohr's salt is prepared by dissolving an equimolar mixture of iron (II) sulfate heptahydrate and ammonium sulfate in water, with a bit of sulfuric acid. The solution is cooled to crystallize the compound, which is removed from the solution, washed and dried. with the unknown strength Mohr’s salt solution and the concordant readings were noted. Observation and Calculations: Weight of the Mohr’s salt dissolved in distilled water: 7.8000 g/L Normality of the solution, N 1 = 7.8000 / 392.14 a) Titration with known strength Mohr’s salt solution: Sl. No. needed (ml) Vol. of Mohr’s salt solution (V 1) Weigh two 0.60 gram samples of Mohr’s salt into two separate 250 mL Erlenmeyer flasks.

The reaction can be shown as follows –. FeSO4 + (NH4)2SO4 + 6H2O 🡪 FeSO4. (NH4)2SO4.6H2O. Mohr's salt is prepared by dissolving an equimolar mixture of hydrated ferrous sulfate and ammonium sulfate in water containing a little sulfuric acid, and then subjecting the resulting solution to crystallization.
