DEFINITIONContent
99.0 per cent to 101.0 per cent (ignited substance).
CHARACTERS
Appearance
Pale pink crystalline powder,
slightly hygroscopic.
Solubility
Freely soluble in water,
practically insoluble in ethanol (96 per cent).
IDENTIFICATION
A. Solution S (see Tests) gives
reaction of sulphates.
B. Dissolve 50 mg in 5 ml of water. Add 0.5 ml of
ammonium sulphide solution. A pale pink
precipitate is formed which dissolves on the addition of 1 ml of anhydrous
acetic acid.
C. Loss on ignition (see Tests).
TESTS
Solution S
Dissolve 10.0 g in distilled
water and dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is not more opalescent
than reference suspension.
Chlorides
Maximum 100 ppm.
Iron
Maximum 10 ppm, determined on
solution S.
Zinc
Maximum 50 ppm.
Heavy metals
Maximum 20 ppm.
Loss on ignition
10.0 per cent to 12.0 per cent, determined on 1.00 g at 500 ± 50C.

MnSO4-4H2O
DEFINITIONManganese Sulphate is manganese(II) sulphate tetrahydrate. It contains not less than 98.0% and not more than 100.5% of MnSO4, calculated with reference to the substance ignited at 450 to 500C.
CHARACTERISTICS
Pale pink crystals or crystalline
powder.
Freely soluble in water;
practically insoluble in ethanol (96%).
IDENTIFICATION
A. Dissolve 0.5 g in 10 ml of water
and add 1 ml of sodium sulphide solution. A pink precipitate is
produced which is soluble in 6M acetic acid.
B. To 0.1 g add 2 g of lead-(IV)
oxide and 5 ml of nitric acid , boil gently for a few minutes, add
100 ml of water and filter. A purple solution is produced.
C. Yields the reactions
characteristic of sulphates.
TESTS
Arsenic
4 ppm
Heavy metals
40 ppm
Iron
40 ppm
Zinc
500 ppm
Chloride
330 ppm
Loss on ignition
When ignited to constant weight at 450° to 500°, loses 31.0 to 34.0% of
its weight. Use 1 g.

Manganese(2+) sulfate (1:1) monohydrate [10034-96-5]
Anhydrous 151.00 [7785-87-7]
Manganese Sulfate contains not less than 98.0 percent and not more than 102.0 percent of MnSO4·H2O.
Identification— A solution (1 in 10) responds to the tests for Manganese 191 and for
Sulfate.
Loss on ignition— Ignite it at 450 to constant weight: it loses
between 10.0% and 13.0% of its weight.
Substances not precipitated by ammonium sulfide— Dissolve 2.0 g in
90 mL of water, add 5 mL of ammonium hydroxide, warm the solution, and pass
hydrogen sulfide through the solution for about 30 minutes. Dilute with water to
100 mL, mix, and allow the precipitate to settle. Decant the supernatant through
a filter, transfer 50 mL of the clear filtrate to a tarred dish, evaporate to
dryness, and ignite, gently at first and finally at 800 ± 25 : the weight of the
residue does not exceed 5 mg (0.5%).
