Abstract

This activity focuses on a familiar reaction, that of sodium bicarbonate with aqueous acetic acid. Students discover the concept of stoichiometry and limiting reactants in two ways: first by adding vinegar to a small quantity of baking soda until bubbles stop, and second by mixing a constant quantity of baking soda with increasing volumes of vinegar and collecting the carbon dioxide produced in balloons.
