Magnesium Peroxide BP Grade
Ph Eur

Mixture of magnesium peroxide and magnesium oxide.
Content: 22.0 per cent to 28.0 per cent of MgO2.

Appearance: White or slightly yellow, amorphous, light powder.
Solubility: Practically insoluble in water and in ethanol (96 per cent). It dissolves in dilute  mineral acids.

A. Dissolve about 15 mg in 2 mL of dilute nitric acid and neutralise with dilute  sodium hydroxide solution. The solution gives the reaction of magnesium.
B. Dissolve 0.1 g in 2 mL of dilute sulfuric acid and dilute to 10 mL with water.  Shake 1 mL of this solution with 5 mL of ether and 0.5 mL of potassium  dichromate solution. The ether layer is blue.

Solution S1: Dissolve cautiously 5.0 g in 40 mL of hydrochloric acid. Cautiously evaporate the  solution to 10 mL and dilute to 100 mL with a mixture of equal volumes of acetic acid  and distilled water. Filter, if necessary, through a previously ignited and tared  porcelain or silica filter crucible of suitable porosity to give a clear filtrate. Keep the  residue for the test for acid insoluble substances.
Solution S2: Dilute 5 mL of solution S1 to 25 mL with distilled water R.
Appearance of solution: Solution S1 is not more intensely coloured than reference solution.
Acidity or alkalinity: To 2.0 g add 100 mL of carbon dioxide-free water and heat to boiling for 5 min.  Filter whilst hot through a sintered-glass filter, allow to cool and dilute to  100 mL with carbon dioxide-free water. To 15 mL of the filtrate, add 0.1 mL of  phenolphthalein solution. The solution is red. Not more than 0.2 mL of 0.1 M  hydrochloric acid  is necessary to change the colour of the indicator. Keep the filtrate  for the test for soluble substances.
Acid insoluble substances: Maximum 0.1 per cent.
Soluble substances: Maximum 1.5 per cent.
Chlorides: Maximum 0.1 per cent.
Sulfates: Maximum 0.5 per cent.
Arsenic: Maximum 4 ppm, determined on 5 mL of solution S1.
Calcium: Maximum 1.0 per cent.
Iron: Maximum 500 ppm.
Heavy metals: Maximum 30 ppm.

Dissolve 80.0 mg, shaking cautiously, in a mixture, previously cooled to 20C, of 10  mL of sulfuric acid and 90 mL of water. Titrate with 0.02 M potassium  permanganate until a pink colour is obtained.
1 mL of 0.02 M potassium permanganate is equivalent to 2.815 mg of MgO2.
