British Pharmacopoeia
Dried Magnesium SulphateDried Magnesium Sulphate BP ( Magnesium Sulfate )
Dried Epsom Salts
Preparation
Magnesium Sulphate PasteDEFINITION
Dried Magnesium Sulphate contains not less than 62.0% and not more than 70.0% of MgSO4.
It may be prepared by drying magnesium sulphate at 100° until it has lost approximately 25% of its weight.CHARACTERISTICS
A white powder.
Freely soluble in water; dissolves more rapidly in hot water.IDENTIFICATION
Yields the reactions characteristic of magnesium salts and of sulphates.TESTS
Acidity or alkalinity
To 10 ml of a 7.5% w/v solution in carbon dioxide-free water add 0.05 ml of phenol red solution. Not more than 0.2 ml of either 0.01M hydrochloric acid VS or 0.01M sodium hydroxide VS is required to change the colour of the solution.
Arsenic
0.33 g dissolved in 25 ml of water complies with the limit test for arsenic, (3 ppm).
Heavy metals
Dissolve 1.3 g in 20 ml of water and add 1 g of ammonium chloride. 12 ml of the resulting solution complies with limit test A for heavy metals, Appendix VII. Use lead standard solution(1 ppm Pb) to prepare the standard (15 ppm).
Iron
0.33 g dissolved in 10 ml of water complies with the limit test for iron, Appendix VII (30 ppm).
Chloride
0.13 g dissolved in 15 ml of water complies with the limit test for chlorides, Appendix VII (400 ppm).
Insoluble matter
7.5 g dissolves in 20 ml of water, producing a solution which may be slightly turbid at first but which becomes clear in a few minutes.

MgSO4,7H2O 246.5 10034-99-8
Action and use
Osmotic laxative; used in treatment of electrolyte deficiency.DEFINITION
Content
99.0 per cent to 100.5 per cent (dried substance).CHARACTERS
Appearance
White or almost white, crystalline powder or brilliant, colourless crystals.
Solubility
Freely soluble in water, very soluble in boiling water, practically insoluble in ethanol (96 per cent).IDENTIFICATION
A. It gives the reactions of sulphates.
B. It gives the reaction of magnesium.TESTS
Solution S
Dissolve 5.0 g in water R and dilute to 50 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
Acidity or alkalinity
To 10 ml of solution S add 0.05 ml of phenol red solution. Not more than 0.2 ml of 0.01 M hydrochloric acid or 0.01 M sodium hydroxide is required to change the colour of the indicator.
Chlorides
Maximum 300 ppm.
Arsenic
Maximum 2 ppm, determined on 0.5 g.
Iron
Maximum 20 ppm.
Heavy metals
Maximum 10 ppm.
Loss on drying
48.0 per cent to 52.0 per cent, determined on 0.500 g by drying in an oven at 110-120°C for 1 h and then at 400°C to constant mass.
