Marble Chips And Hydrochloric Acid Experiment Equation

The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.

Marble chips and hydrochloric acid experiment equation.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. 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. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.

The rate of this reaction can be changed by changing the size of the marble chips. 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.
