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
