The aim of the experiment is to prepare mohr's salt solution and crystals. Mohr's salt is an example of a ‘double salt’ and it is simple to prepare because it is less soluble than either of its constituent salts.

Calculations. (a) Normality of the KMnO 4 solution. x ml of the given KMnO 4 solution are equivalent to 20 ml of N/20 Mohr’s salt solution.

WORKPLACE EXPOSURE LIMITS. The following exposure limits are for soluble Iron salts Salt (2:2:1). Other Names: Mohr's Salt; Ammonium Iron Sulfate.

Mohrs salt

Weigh the clean and dry watch glass and record its weight in the note-book. Weigh accurately 4.9 g of Mohr’s salt crystals on the watch glass and record the weight in the note-book. Transfer carefully the weighed Mohr’s salt from the watch glass into a clean 250 ml beaker. The formula for Mohr's salt is - (NH4)2Fe(SO4)2·6H2O It is chemically, ammonium iron(II) sulfate. It is the inorganic compound containing two different cations, Fe²+ and NH₄+.

This compound is known to contain two primary cations, namely the ammonium cation (denoted by NH 4+) and the ferrous cation (denoted by Fe 2+ ). Therefore, Mohr’s salt can be categorized as a double salt of ammonium sulfate and ferrous sulfate.

Saltet er mer luftbestandig enn rent jern(II)sulfat og blir derfor brukt i titrimetri for å innstille kaliumpermanganatløsninger på en bestemt jernverdi. På grunn av lysømfintlige egenskaper ble også Mohrs salt brukt i fotografisk industri. Mohr method 1. Precipitation method Adit Muktadir 2. Introduction This method determines the chloride ion concentration of a solution by titration with silver nitrate.
