Marble chips and hydrochloric acid experiment equation.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
The rate of this reaction can be changed by changing the size of the marble chips.
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.
