(d) Mohr's salt, (NH 4) 2 Fe(SO 4) 2•xH 2O, is the hydrated form of ammonium iron(II) sulfate. x represents the number of moles of water in 1 mole of the salt. A student wanted to determine the value of x. 0.784 g of the hydrated salt was dissolved in water and this solution was acidiied.

In this titration Mohr’s salt acts as reducing agent and potassium permanganate works as oxidizing agent. So, the reaction between Mohr’s salt and KMnO4 is a redox reaction in which oxidation and reduction takes place simultaneously. ammoniumjonen i Mohrs salt förhindrar denna reaktion och saltet kan lagras under lång tid utan att Fe2+-jonerna påverkas. Mohrs salt används ibland som ett gräsförbättringsmedel: ammoniumjonerna tillför gödningsämnet kväve och järnjonerna dödar eventuell förekomst av mossa. Förberedelser Läs igenom hela instruktionen.

So, the reaction between Mohr's salt and potassium permanganate is a redox reaction. In this redox reaction, ferrous ion from Mohr's salt gets oxidised and pink

In this redox reaction, ferrous ion from Mohr’s salt gets oxidised and pink coloured of manganese present in potassium permanganate, which is in the +7 oxidation state gets reduced to colourless Mn 2+ state. Mohr’s salt titration with potassium permanganate is also a redox titration. In this titration Mohr’s salt acts as reducing agent and potassium permanganate works as oxidizing agent. So, the reaction between Mohr’s salt and KMnO4 is a redox reaction in which oxidation and reduction takes place simultaneously.

Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid of Ferrous Ammonium Sulphate which is popularly known as Mohr's salt.

Mohr’s salt is named after the German chemist, Karl Freidrich Mohr, who made many important advances in the methodology of titration in the 19th century. It is a double salt. A double salt is a substance obtained by the combination of two, different salts which crystallizes together as a single substance but ionize as two distinct salts when dissolved in water.
