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.

(NH4)2SO4.6H2O 6Fe2++Cr2O2−7+14H+⟶6Fe3++2Cr3+7H2O Mohr's salt [FeSO4. The Mohr method for determination of chloride in water is a pH sophisticated method. It must be perform between the pH levels 6.5-9.0. It is better to carry out between the pH ranges 7-8. At upper pH level, the silver ions react with hydroxide ions and precipitated as silver hydroxide. Mohr’s salt chemically known as Ammonium iron (II) sulfate having the formula FeSO4(NH4)2SO4.6H2O has molar mass 392gmol-1.

Sulfuric acid is commonly added to solutions to reduce oxidation to ferric iron. It is used in the Fricke's dosemeter to measure high doses of gamma rays.

2017-05-09 · The reaction between KMnO 4 and Mohr’s Salt is a redox reaction in which KMnO 4 acts as an oxidizing agent oxidizes the Fe 2+ ions to Fe 3+ ions in acidic medium. The end of the reaction is indicated by the appearance of light pink color. 2011-01-28 · You'll observe that your "Mohr solution" will become yellow in colour, i.e., it won't remain "Mohr salt solution" anymore, hence can't be used in titration. And while doing the titration of the Mohr salt solution with KMnO4 (or even with K2Cr2O7), you need to add dilute H2SO4.
