5 Questions
What are the products formed when an acid reacts with a metal carbonate?
Salt, carbon dioxide, and water.
What is the equation for the reaction between calcium hydroxide and carbon dioxide gas?
Ca(OH)2(aq) + CO2(g) -> CaCO3(s) + H2O(l)
What is the test for carbon dioxide gas?
When CO2 gas is passed through lime water, it turns milky due to the formation of calcium carbonate.
What are non-metallic oxides?
Non-metallic oxides are acidic in nature.
What happens when acids are dissolved in water?
Acids release hydrogen ions (H+) in water, which combine with water molecules to form hydronium ions (H3O+).
Study Notes
Acid and Metal Carbonate Reaction
- When an acid reacts with a metal carbonate, the products formed are a salt, water, and carbon dioxide gas.
Reaction Between Calcium Hydroxide and Carbon Dioxide
- The equation for the reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide gas (CO2) is: Ca(OH)2 + CO2 → CaCO3 + H2O.
Test for Carbon Dioxide
- The test for carbon dioxide gas is to bubble it through limewater, which will turn milky white due to the formation of calcium carbonate.
Non-Metallic Oxides
- Non-metallic oxides are oxides that do not contain metals, such as carbon dioxide (CO2) and sulfur dioxide (SO2).
Acids in Water
- When acids are dissolved in water, they dissociate into hydrogen ions (H+) and anions.
