End Point Colourless to permanent pink (KMnO4 in burette). Procedure Rinse and fill the burette with the given KMnO4 solution. Weigh exactly 4.90 g of Mohr’s salt crystals and […] 2. The Mohr titration should be carried out under conditions of pH 6.5 – 9.

In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent.

Mohr salt n factor

Dear student, n-factor is the just the number of electrons supplied/ reacted with one mole of the substance. Mohr's salt is - FeSO4.

The hexahydrate form can be represented by the chemical formula Fe(SO 4)(NH 4) 2 (SO 4).6H 2 O. The molar mass of Mohr’s salt (in its anhydrous state) is equal to 284.05 grams per mole. The hexahydrate of Mohr’s salt is known to have a molar mass of 392.13 grams per mole. Mohr’s salt or ammonium ferrous sulphate is the inorganic compound with the formula (NH4)2 Fe (SO4)2.6H2O containing two different cations Fe2+ and NH4+. It is classified as a double salt of ferrous sulphate and ammonium sulphate.

It is classified as a double salt of ferrous sulphate and ammonium sulphate.

Dear Student, Mohr's salt is FeSO 4 (NH 4) 2 SO 4 . 6H 2 O On it's reaction with H 3 PO 4 Fe gets oxidised from Fe +2 to Fe +3. Therefore, n-factor for mohr's salt will be 1 equivalent weight = molecular weight/ n- factor The Mohr method uses chromate ions as an indicator in the titration of chloride ions with a silver nitrate standard solution. After all the chloride has been precipitated as white silver chloride, the first excess of titrant results in the formation of a silver chromate precipitate, which signals the end point (1).

n factor of Fe2+ =1. So, to reduce one mole of dichromate, 6 moles of Fe2+ are required. Hence, the correct option is D.

So, the reaction between Mohr’s salt and KMnO 4 is a redox reaction in which oxidation and reduction takes place simultaneously.
