Questions & Answers

Q: What are the products of the reaction between calcium carbonate and hydrochloric acid?

The products of this reaction are calcium chloride, water, and carbon dioxide. Calcium chloride is soluble in water, while carbonic acid decomposes to water and carbon dioxide.

Q: Is calcium chloride soluble or insoluble in water?

Calcium chloride is soluble in water. However, there are exceptions where chlorides bonded to silver, mercury, or lead are insoluble.

Q: Why does carbonic acid decompose in acidic environments?

Carbonic acid decomposes in acidic environments because it is an unstable compound. Its decomposition results in the formation of water and carbon dioxide.

Q: How do you write the net ionic equation for this reaction?

To write the net ionic equation, you first balance the molecular equation, then write the total ionic equation by breaking down compounds into their respective ions. Finally, eliminate the spectator ions to obtain the net ionic equation.

Summary & Key Takeaways

• The reaction between calcium carbonate and hydrochloric acid results in the formation of calcium chloride, water, and carbon dioxide.

• Calcium chloride is soluble in water, while carbonate combines with hydrogen to form carbonic acid, which decomposes to water and carbon dioxide.

• The equation needs to be balanced, and the total ionic equation is written by breaking down the compounds into their respective ions.
