Reaction 1: Chalk is heated strongly. Carbon dioxide gas is released leaving calcium oxide. Filtering the mixture will separate a solution of calcium hydroxide (the filtrate). Reaction 3: When carbon dioxide gas is passed through the calcium hydroxide solution a white precipitate is formed.
What happens when you mix chalk and vinegar?
Sidewalk chalk contains a compound called calcium carbonate (CaCO3), which reacts with vinegar (acetic acid, CH3COOH) to form the gas carbon dioxide (CO2). This is because the reaction needs to have vinegar and chalk molecules colliding together to complete.
