1. Write the chemical equation for the
reaction of an antacid containing magnesium hydroxide,
Mg(OH)2, with stomach acid (hydrochloric acid, HCl) and
then balance the equation.
2. If a tablet of the antacid
neutralized 41.4 mL of 0.150 M hydrochloric acid then how many
grams of magnesium hydroxide was in the tablet?
(Show calculation)
3.Concentrated gastric acid is about
0.16 molar in concentration (0.16 M HCl), corresponding to a pH of
0.8. In the stomach, however, the solution becomes diluted...
