Question

determine the molarity of the given KMno4 solution with the help of supplied m_20 mohr s salt solution by titration method ​

Answer 1

Answer:

Titration Method

Explanation:

In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent. Mohr’s salt is a double salt of ferrous sulphate and ammonium sulphate and its composition is FeSO4.(NH4)2SO4.6H2O. It is a primary standard. Therefore, its standard solution can be prepared directly. Ferrous ions of Mohr’s salt undergo hydrolysis in aqueous solution. To prevent the hydrolysis, Conc. H2SO4 needs to be added to the Mohr’s salt crystals during the preparation of its standard solution.

In this titration, the MnO4- ion is reduced to Mn2+ in the presence of acid and Fe2+ ions of Mohr’s salt is oxidized to Fe3+
