Marble chips and hydrochloric acid experiment equation.
Hcl calcium carbonate calcium chloride carbon dioxide water.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
The rate of this reaction can be changed by changing the size of the marble chips.
An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid.
A graph of decrease in mass against time is shown in fig.
