The chemical Mohr’s salt formula of the double salt is FeSO 4.(NH 4) 2 SO 4.6H 2 O (Ferrous Ammonium Sulfate Hexa Hydrate) or (NH 4) 2 Fe(SO 4) 2.6H 2 O (Ammonium Iron(II) Sulphate).Its name derived from the name of German Chemist Karl Friedrich Mohr, who proposed various important approaches of titration in the 19th century.

Therefore n- factor = 1. (1 electron is removed per mole of Mohr's salt). Mohr’s Salt, also referred to as ammonium iron (II) sulfate, is an inorganic compound whose chemical formula is represented as (NH 4) 2 Fe (SO 4) 2 (H 2 O) 6. 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+). n-factor of mohr s sal i.e. FeSO4.

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. 3.

RESULTS AND DISCUSSIONAs a part of our continual efforts toward the development of novel, efficient, and green procedures for organic reactions, [15][16][17][18] we turned our attention toward the condensation of 4-hydroxycoumarin (1) and aromatic aldehydes 2 in the presence of Mohr's salt hexahydrate as catalyst to produce bis-4-hydroxycoumarin derivatives 3 (Scheme I). 19 To identify the Mohr's salt is - FeSO4.(NH4)2SO4.6H2O. In Mohr's salt Fe is in +2 state (Fe2 +) , it oxidises by removing 1 electron and converts to Fe3 +. Therefore n- factor = 1.
