The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Marble chips and hydrochloric acid experiment equation. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases.
