2. What observations would you note after adding bromide ions to concentrated sulfuric acid?
- Steamy fumes and eggy smell
- No change
- Steamy fumes and brown vapour
- Solid bromine
3. Why do we add acid to silver nitrate solution before using it to test for halide ions?
- To remove sulfate ions which would give a false result
- To remove carbonate ions which would give a false result of a white precipitate
- To make it easier to see a precipitate
- To help dissolve the halide ions
4. What colour precipitate does bromine form?
- Pale yellow
- Cream
- White
- None- silver bromide is very soluble
5. Which halide will not form a precipitate in silver nitrate solution?
- Iodide
- Fluoride
- Bromide
- Chloride
