If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases.
Marble chips and hydrochloric acid experiment equation.
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.

How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
A graph of decrease in mass against time is shown in fig.
The rate of this reaction can be changed by changing the size of the marble chips.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
