|Ingredients||Qty Given||Qty Taken||Activity|
|Magnesium Sulphate||100g||Formation of Magnesium Hydroxide|
|Light Magnesium oxide||52.5g|
|Peppermint Oil||0.5ml||Flavouring Agent|
|Purified water freshly boiled and cooled||q.s to 1000 ml||Vehicle|
Sodium hydroxide was dissolved in purified water.
Light magnesium oxide was triturated with this solution to form a smooth cream.
Pour this suspension in a thin stream into a solution of the magnesium sulfate in purified water, stirring continuously during the mixing.
Mixture is set aside in a closed container for 48 hrs.
Allow the precipitate to subside, remove the clear liquid, and wash the precipitate with purified water until the washings give only a slight reaction for sulfate.
Mix the washed precipitate with purified water, and add sufficient purified water to produce the required volume.
MgO +H2O Mg (OH)2
This is a Hydration reaction which is very slow
Mg SO4 +2 NaOH Mg (OH)2 + Na2SO4
Precipitation reaction by double decomposition
All sulphate ions ( Na2SO4) must be removed as they enhance peristalsis of intestine.
Laxative (8-16 ml) and antacid (1-4 ml)
Container & storage:
Well closed container in a cool place
Shake well before use
