Marble Chips And Hydrochloric Acid Experiment Equation

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

Marble chips and hydrochloric acid experiment equation.

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. 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.

A graph of decrease in mass against time is shown in fig. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. Hcl calcium carbonate calcium chloride carbon dioxide water. If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases.
