Magnesium Sulfate, rendered anhydrous by ignition, contains not less than 99.0 percent and not more than 100.5 percent of MgSO4.

Identification: A solution (1 in 20) resonds to the tests for Magnesium and for Sulfate.
pH: between 5.0 and 9.2, in a solution (1 in 20).
Loss on drying: Dry it at 105 for 2 hours: the anhydrous form loses not more than 2% of its weight.
Loss on ignition: Weigh accurately about 1 g in a crucible, heat at 105 for 2 hours, then ignite in a muffle furnace at 450 ± 25 to constant weight: the monohydrate loses between 13.0% and 16.0% of its weight, the dried form loses between 22.0% and 28.0% of its weight, and the heptahydrate loses between 40.0% and 52.0% of its weight.

Iron:
FOR MAGNESIUM SULFATE INTENDED FOR USE IN PREPARING NON-PARENTERAL DOSAGE FORMS:
Dissolve 0.50 g in 40 mL of water and proceed as directed in the test for Iron: the limit is 20 µg per g.
FOR MAGNESIUM SULFATE INTENDED FOR USE IN PREPARING PARENTERAL DOSAGE FORMS: the limit is 0.5 µg per g.
Heavy metals: Dissolve 2 g in 25 mL of water: the limit is 0.001%.

Dried Magnesium Sulphate BP Magnesium Sulfate
Dried Epsom Salts or Magnesium Sulphate Dried

DEFINITION
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 100C 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.

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.

Magnesium Sulphate Heptahydrate Monohydrate Anhydrous Dried Suppliers:

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.

They assign the credit of their hard work to your blessings
They keep you amused.

They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.

They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.

They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.

They offer you a small bribe as advance for booty, called lottery
They love to dream.

I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
