Determination Of Concentration Of Kmno4 Soution Using Ferrous ођ Procedure: (a) preparation of 0.05m standard solution of ferrous ammonium sulfate: the quantity of mohr’s salt required for the 250ml of the solution having a normality of 0.05n can be calculated as follows. the molar mass of mohr’s salt = 392 g mol. strength = normality x equivalent weight. = (1 20) x 392 = 19.6 g l.

Mohr Salt Titration With Kmno4 Cbse Chemistry Practicals Class 12 As a result, this ferrous ammonium sulphate is not heated prior to titration. download class 12 chemistry viva questions on determination of concentration molarity of kmno4 solution by titrating it against a standard solution of – ferrous ammonium sulphate by clicking on the button below. download pdf. read also: mohr salt titration with kmno4. 10ml of ferrous ammonium sulfate (mohr’s salt) sulfuric acid is poured into the conical flask. kmno4 acts as a self indicator. colourless to permanent pale pink colour is the endpoint. (image will be uploaded soon) a. preparation of 250ml of m 20 solution of mohr’s salt –. the molar mass of mohr’s salt is 392gmol 1. Mohr salt, on the other hand, is a double salt that forms a single crystalline structure with the formula feso 4.(nh 4) 2 so 4.6h 2 o, also known as ferrous ammonium sulfate. mohr salt serves as a reducing agent in this titration, while potassium permanganate acts as an oxidising agent. Volumetric analysisaim: to prepare m 40 mohr’s salt (ferrous ammonium sulphate) solution and determine the molarity and strength of given potassium permang.
