Answer 1

Answer:

Explanation:

To prepare M/20 Mohr salt solution and to determine the molarity and strength of the given potassium permanganate solution.

(b ) Titration of Mohr's salt against KMnO4 solution

Answer 2

molarity of the given KMnO4 solution by using titration method

Explanation:

• Potassium permanganate acts as an oxidizer, whereas Mohr's salt acts as a reducing agent in this titration.

• FeSO4.(NH4)2SO4.6H2O is the formula for Mohr's salt, which is a double salt of ferrous sulphate and ammonium sulphate.

• It's a foundational requirement. As a result, it is possible to prepare its standard solution right away. In an aqueous solution, the ferrous ions of Mohr's salt hydrolyze.

• During the manufacture of Mohr's salt crystals' standard solution, Conc. H2SO4 must be added to avoid hydrolysis.

• In the presence of acid, the MnO4- ion is reduced to Mn2+, and the Fe2+ ions in Mohr's salt are oxidised to Fe3+ in this titration.

hence, this is the molarity of the given KMnO4 solution
