Acid-Carbonate Reaction Concepts

The video tutorial demonstrates the reaction between hydrochloric acid and calcium carbonate, resulting in the formation of a salt, carbon dioxide, and water. The experiment involves using lime water to test for carbon dioxide production. The process includes setting up test tubes with reactants, observing effervescence, and noting the formation of a white precipitate in lime water. The video concludes with a recap of the reaction process.

What are the products formed when an acid reacts with a carbonate?

• Salt, carbon dioxide, and water

• Salt, oxygen, and water

• Salt, hydrogen, and water

• Salt, nitrogen, and water

Which acid is used in the reaction demonstrated in the video?

• Sulfuric acid

• Nitric acid

• Hydrochloric acid

• Acetic acid

What is the first step in the experimental procedure?

• Add calcium carbonate to a test tube

• Place a stopper with a delivery tube

• Fill a test tube with lime water

• Add hydrochloric acid to a test tube

To what depth should the test tube be filled with hydrochloric acid?

• 4 cm

• 1 cm

• 3 cm

• 2 cm

What is observed when hydrochloric acid is added to calcium carbonate?

• Effervescence and gas production

• A color change

• No reaction

• Formation of a solid

What happens to the gas produced when it is passed through lime water?

• It forms a clear solution

• It forms a white precipitate

• It forms a blue solution

• It forms a red precipitate
