Question

How can I tell that there is a chemical reaction between Hydrochloric Acid and Calcium Carbonate when they are in a beaker on scales?

Answer 1

Answer:

Explanation:

Like all metal carbonates, calcium carbonate reacts with acidic solutions to produce carbon dioxide gas. It is this reaction that is responsible for limestone fizzing when dilute hydrochloric acid is placed on its surface. Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide and water.

1.,To investigate the effect of changing the conditions on the rate of a reaction.

2.Calcium carbonate reacts with dilute hydrochloric acid:

3.Calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide.

4.The volume of carbon dioxide gas produced can be measured using a gas syringe.
