2. If a patient had an elevated blood pressure level and had been advised to restrict his or her sodium
intake, which antacid(s) would you recommend for such a patient
3. Explain the technique of back-titration.
4. Some antacids will generate carbon dioxide, CO2, when they neutralize the acid in gastric juice.
Write the net ionic equation for the reaction of the antacid containing the anion carbonate, CO , or
the anion bicarbonate, HCO3, with acid (H+).
5. Write the net ionic equation for the neutralization of the bases, magnesium hydroxide, Mg(OH)2, and
aluminum hydroxide, Al(OH)3, found in Maalox, for example, with acid (H*).
