Marble Chips And Hydrochloric Acid Experiment Equation

A graph of decrease in mass against time is shown in fig.

Marble chips and hydrochloric acid experiment equation.

If dilute hydrochloric acid is added to excess marble chips carbon dioxide is given off and the mass of reactants decreases. 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. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. 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. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of the marble chips. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
