What does the milk of magnesia do?
Milk of magnesia is used as an antacid or a laxative. Milk of magnesia is alkaline, which means that it would neutralize any acidic substance encountered. Hence, it is an excellent antacid. It neutralizes excess stomach acid or hydrochloric acid. The hydroxide ions of the milk combine with the hydrogen ions in the stomach acid to reduce excess acidity in the stomach.
The magnesium ions in the milk of magnesia withdraw water from the surrounding tissues via osmosis. The extra water pooled in the intestines softens and bulks up the feces that, in turn, stimulates its nerves. The magnesium ions increase the water and electrolyte content in the intestine, resulting in intestinal motility.
