5 Questions
What happens when carbonate reacts with acid?
It forms carbon dioxide, salt, and water
What happens to lime water when exposed to carbon dioxide gas?
It turns cloudy
What is the test for carbonates?
Add dilute hydrochloric acid and run the gas produced through lime water
What happens when silver nitrate is added to halide ions?
It forms a white precipitate

The silver nitrate test
Study Notes
- The video covers tests for anions including carbonate, sulfate, and halide ions.
- Carbonate reacts with acid to form carbon dioxide, salt, and water.
- Lime water turns cloudy when exposed to carbon dioxide gas.
- To test for carbonates, dilute hydrochloric acid is added to the sample and the gas produced is run through lime water.
- A white precipitate forms when barium ions react with sulfate ions.
- Dilute hydrochloric acid is added to remove impurities before adding barium chloride solution.
- Dilute nitric acid is added to remove impurities in the halide test.
- Silver nitrate is added to react with halide ions and form a precipitate.
- The color of the precipitate depends on the type of halide ion present.
- The halide test is also called the silver nitrate test.
