  1. 1What reagent is used to test for sulphate ions in a solution, and what is the positive result?
    1. ABarium sulphate. Positive result is a white precipitate
    2. BAcidified silver nitrate. Positive result is a yellow precipitate
    3. CNitric acid. Positive result is a cream precipitate
    4. DBarium chloride. Positive result is a white precipitate
  2. 2Which of the following is NOT a reagent that could be used to distinguish between butanone and 2-methylbutanal?
    1. ABromine water
    2. BTollens' reagent
    3. CAcidified potassium dichromate(VI)
    4. DFehling's reagent
    5. EBenedict's reagent

    1. ASteamy fumes
    2. BBrown solid
    3. CWhite precipitate
    4. DBrown gas
  4. 4State the observation you would make when iodine is added to potassium bromide.
    1. ARed-brown solution forms
    2. BNo change
    3. COrange-brown solution forms
    4. DBlack solid forms
  5. 5X and Y are functional group isomers with the molecular formula C6H12. Identify all possible reagents that you could use to distinguish between them.
    1. ATollens' reagent
    2. BAcidified potassium(VI) dichromate
    3. CBromine water

  6. 6The solubility of silver halides in ammonia decreases going down Group 7.
    1. ATrue
    2. BFalse
  7. 7What observations would be made when solid silver iodide is added to concentrated sulphuric acid? Select all that apply.
    1. ASmell of bad eggs
    2. BPurple solid
    3. CYellow solid
    4. DSteamy fumes
  8. 8X is the inorganic product of the reaction of potassium cyanide with a haloalkane. When added to acidified silver nitrate X forms a white-cream precipitate. The precipitate was found to be insoluble in dilute ammonia but dissolved in concentrated ammonia. Deduce the identity of X.
