C3 - Tests for negative ions
- Testing for carbonates - check for CO2
- You can test to see if a gas is carbon dioxide by bubbling it through
limewater. If it is carbon dioxide, the limewater turns cloudy
- You can use this to test for carbonate ions since
carbonate react with dilute acids to form carbon dioxide
- acid + carbonate = salt + water + carbon dioxide
- acid + carbonate = salt + water + carbon dioxide
- You can test to see if a gas is carbon dioxide by bubbling it through
limewater. If it is carbon dioxide, the limewater turns cloudy
- Tests for halides
- To test for chloride,bromide or iodide, add dilute nitric acid followed by silver nitrate solution
- Chloride gives a white precipitate of silver chloride
- Bromide gives a cream precipitate of silver bromide
- Iodide gives a yellow precipitate of silver iodide.
- Chloride gives a white precipitate of silver chloride
- To test for chloride,bromide or iodide, add dilute nitric acid followed by silver nitrate solution
- To test for sulphate ions
- Add dilute HCl followed by barium chloride solution
- A white precipitate of barium sulphate means the original compound was a sulphate.
- Add dilute HCl followed by barium chloride solution
