Mohr’s Salt found in: Ammonium iron(II) sulfate hexahydrate, BioXtra, =98%, Fluka Ammonium iron(II) sulfate hexahydrate ACS reagent, 99%, Ammonium iron(II).. 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 Mohr’s salt is a double salt made up of both ammonium and iron (II) ions in a 1:1 ratio. It is also called iron (II) ammonium sulfate. Part of the reason I was so excited was because Mohr’s salt is supposedly much more stable compared to pure iron (II) sulfate. This means it does not oxidize and turn brown easily.

medium is oxidation–reduction or redox reaction where potassium permanganate solution is the oxidizing agent and Mohr's salt solution is the reducing agent.
