Question

n factor for mohrs salt

Answer 1

Cias,
******
Mohr's salt is - FeSO4.(NH4)2SO4.6H2O. In Mohr's salt Fe is in +2 state (Fe2 +) , it oxidises by removing 1 electron and converts to Fe3 +. Therefore n- factor = 1. ( 1 electron is removed per mole of Mohr's salt).

Answer 2

We all know that the acid and acidic compounds produce H+ ions when they are dissolved in an aqueous solution.

Now the number of H+ ions produced by one mole of acid or acidic compound ,is the N-factor of that acid nor acidic compound.

Similarly the chemical formula of Mohr's salt is ;

FeSO4.(NH4)2SO4.6H2O

In this chemical compound the Fe molecule has a dual positive charge (+2).

And this Fe molecule is able to eliminate one electron to gain a configuration of Fe³+ .

So the N-factor of Mohr's salt is 1.
