Science Alive: Chemical Reactions and How You Know When You've Made Something

Curated by ACT

In this activity, students carry out a chemical reaction in which two reactants (baking soda and hydrochloric acid) produce three products (sodium chloride, carbon dioxide gas, and water) and determine that the solid product (sodium chloride) is not the same as the solid reactant (baking soda). The hydrochloric acid, the water, and the carbon dioxide gas are not accounted for by mass; the water and gas are driven off. Conservation of mass is not illustrated here.
