Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
Marble chips and hydrochloric acid experiment equation.
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.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Hcl calcium carbonate calcium chloride carbon dioxide water.
A graph of decrease in mass against time is shown in fig.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
The rate of this reaction can be changed by changing the size of the marble chips.
