Titration To Determine Molarity Of Kmno4 Titrating It Against 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. 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.
Titration Of Kmno4 Vs Ferrous Ammonium Sulphate Redox Titration How To @a2zpractical991 class 12th physics all practical playlist link playlist?list=pluqt1pge92w0qfpaoy wa1dzarrvejzljclass 12th chemistry all. The procedure for this experiment involves the preparation of a 0.05m standard solution of ferrous ammonium sulfate and the titration of the potassium permanganate solution against the standard ferrous ammonium sulfate (mohr’s salt) solution. it is essential to follow the steps carefully to achieve accurate results. It may also decompose into ferrous oxide when heated. 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. Using the law of equivalents (n1×m1×v1 = n2×m2×v2) find the molarity and also strength of the unknown solution. this process is called titration. experiment no. 1. objective : to determine the strengh of a given potassium permanganate solution against a 0.05m standard ferrous ammonium sulphate (mohr’s salt) solution.
