Question

suppose a persons stomach wall was irritated by an over-secretion of stomach acid. why do you think a person would take milk of magnesia, a basic solution? explain your answer in terms of pH.

Answer 1

The pH of stomach secretion is low. This means it is acidic. Too much production can corrode the stomach wall. Therefore in such a situation drinking a basic solution with a higher pH neutralizes some of the stomach acidic secretions hence relieving the effect;

Acid + Base - Salt + Water
