Question

What do you think will be the pH of an antacid solution?

Less than 7 or more than 7.

Answer 1

The pH of an antacid solution would be more than 7. Antacids are weak bases (like magnesium hydroxide or sodium bicarbonate) designed to neutralise the excess hydrochloric acid in your stomach. Because they are basic, their solutions are on the alkaline side of the (pH) scale, typically ranging from 8 to 10.
