Measures of Concentration: Molality and Other Calculations

Question 1

The main acid in the stomach is hydrochloric acid (HCl). Which chemical equations show a reaction that occurs when someone takes an antacid? Check all that apply.

Revolt · Accepted Answer

B: 2HCl + CaCO3 CaCl2 + CO2 + H2O; C: 2HCl + Mg(OH)2 MgCl2 + 2H2O; E: HCl + NaHCO3 NaCl + H2O + CO2

Question 2

Revolt · Accepted Answer

Antacids often contain calcium carbonate, which provides carbonate ions that act as a base. These carbonate ions neutralize stomach acid by accepting free hydrogen ions (H+). This chemical reaction produces water and carbon dioxide gas as products. If the antacid is dissolved before ingestion, the reaction occurs more quickly because the ions are more readily available to react.
