Question

The concentration of a sample of milk of magnesia ,Mg(OH)2, was determined by titration with phosphorus acid (H3PO4) . 30ml of milk of magnesia .required 54.8ml of 0.5 phosphoric acid to neutralise it . The equation is shown below
2H3P04 + 3Mg = 6H20 +Mg3(P04)2

Explanation:

Magnesium Hydroxide BP 415 mg per 5 ml suspension.

Milk of magnesia is quite safe and can be taken daily without problems by patients with occasional constipation, heartburn, or dyspepsia. The most common side effect is diarrhea, although this is the desired effect for patients with constipation.

water, it is often called milk of magnesia because of its milk-like appearance. ... Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, magnesium hydroxide is considered a strong electrolyte. Its low solubility makes it a weak base.
