Marble Chips And Hydrochloric Acid Experiment Equation

Hcl calcium carbonate calcium chloride carbon dioxide water.

Marble chips and hydrochloric acid experiment equation.

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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. 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.

If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases. 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. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
