So that we get the Mohr salt crystall that has bluegreen color because the reaction between Fe and (NH4)2SO4(aq) that formed complex compound. The reaction is; FeSO4(aq) + (NH4)2SO4(aq) (NH4)2 Fe (SO4 ) 2.6H2O(s) The redox reaction, Cr2O2−7 oxidises Mohr's salt, FeSO4. (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.

In this reaction ferrous sulphate is oxidized to ferric sulphate, while, ammonium sulphate remains unreacted.

Mohr’s salt. This double salt is more stable than FeSO 4 alone and is used as reducing agent in redox fitration. During redox reaction Fe +2 ions mohr’s salt is oxidised to Fe +3 ions. Mohr’s salt, cone.

In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent. Weigh two 0.60 gram samples of Mohr’s salt into two separate 250 mL Erlenmeyer flasks. To each flask add 50 mL of the 1 M H2SO4 and swirl to dissolve the salt.

AND CHENNEY, S. 2000. Cartoon Salt Lake City. 48. When dissolved in water, Mohr’s salt (like most other salts of ferrous sulfate) dissolves to yield an aquo complex with the chemical formula [Fe (H 2 O) 6] 2+.

Weight of Mohr's salt required to prepare 1000 ml of 1 M solution = 392 g. Therefore, weight of Mohr's salt required to prepare 250 ml 0.05 M Mohr's salt solution = Determination of strength of KMnO 4 using standard solution of Mohr's salt.
