Marble Chips And Hydrochloric Acid Experiment Equation

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.

Marble chips and hydrochloric acid experiment equation.

Hcl calcium carbonate calcium chloride carbon dioxide water. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

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. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. A graph of decrease in mass against time is shown in fig.
