q/f garlic salt 1kg 2021-04-09 Mohr's salt is prepared by dissolving an equimolar mixture of hydrated ferrous sulfate and ammonium sulfate in water containing a little sulfuric acid, and then subjecting the resulting solution to crystallization. Ferrous ammonium sulfate forms light green crystals. This salt when heated ionises to give all cations and anions present in it. Mohr’s Salt Preparation of Mohr’s Salt.

Mohrs salt är ett s.k. dubbelsalt, d.v.s. det innehåller tre joner som samkristalliserat till en stabil fast fas. Dubbelsalt är alltså bara associerade i fast fas och när man löser upp dem så frisätts de ingående jonerna. Mohrs salt är uppkallat efter den tyske kemisten Karl Friedrich Mohr (1806-1879). Synonym: Ammonium ferrous sulfate hexahydrate, Ammonium iron(II) sulfate, Mohr’s salt Linear Formula: (NH 4 ) 2 Fe(SO 4 ) 2 · 6H 2 O Molecular Weight: 392.14 Steps involved in the preparation of Mohr's salt Place a clean 100 mL beaker onto a top-pan balance, and set the display to read zero, this is known as taking the Weigh directly into the beaker iron (II) sulfate heptahydrate (FeSO4.7H2O; 12.5g) from the reagent bottle.

Ammonium iron (II) sulfate, more commonly referred to as Mohr's salt, is an inorganic chemical compound with the formula (NH4)2Fe (SO4)2·6 H2O as hexahydrate. Containing two different cations, Fe 2+ and NH 4+, it is classified as a double salt of ferrous sulfate and ammonium sulfate. Mohr salt is the double salt that contains of ferro sulphate salt and ammonium sulphate salt in a monocline crystall and has a blue-green colour.

2. The Mohr titration should be carried out under conditions of pH 6.5 – 9. At higher pH silver ions may be removed by precipitation with hydroxide ions, and at low pH chromate ions may be removed by an acid-base reaction to form hydrogen chromate ions or dichromate ions, affecting the accuracy of the end point.
