Calcium carbonate is a common ingredient in antacids that reduces the discomfort associated with acidic stomach or heartburn. Stomach acid is hydrocholoric acid, HCl.HCl.
What volume in milliliters (mL) of an HClHCl solution with a pH of 1.581.58 can be neutralized by 20.0 mg20.0 mg of CaCO3?
If the stomach contains 24.3 mL24.3 mL of pH 1.58pH 1.58 solution, will all of the acid be neutralized?
yes
no
What percentage of the acid is neutralized? If all of the acid is neutralized enter 100%.
Homework Answers
Answer:-
This question is solved by using the simple concept of stoichiometry. Firstly a balanced chemical equation is written then volume is calculated.

8. When a calcium carbonate tablet is ingested, it dissolves by the reaction of stomach acid, which contains hydrochloric acid. The unbalanced equation for this reaction is CaCO,(s) + HCl(aq) -----> CaCl(aq) + H2O(l) + CO.(g). Normal stomach acid contains 5.50% hydrochloric acid. If a particular individual required 13 calcium carbonate tablets to completely neutralize their stomach acid, how many grams of stomach acid reacted? Each calcium carbonate tablet contains 500. mg of the active ingredient.

A common base found at home is milk of magnesia (antacids are bases). The active ingredient of milk of magnesia is magnesium hydroxide, a weak base. Magnesium hydroxide is used to neutralize excess stomach acid which is primarily HCl. How much HCl (in mg) could be neutralized from a normal dose of milk of magnesia if that dose contains 400 mg of Mg(OH)2? The correct answer is 500 mg but could you show your work so i understand how to...
