, 3 This question is about compounds containing elements from Group 7.
(a) Which change occurs when concentrated sulfuric acid is
added to potassium bromide?
(1)
A bromide ions oxidise sulfuric acid forming sulfur
B bromide ions oxidise sulfuric acid forming sulfur dioxide
C bromide ions reduce sulfuric acid forming sulfur
D bromide ions reduce sulfuric acid forming sulfur dioxide
(b) Chemists can test for the presence of bromide ions in solution by adding a
small amount of acidified silver nitrate solution.
The solubility of the precipitate in aqueous ammonia is then tested.
(i) Which statement is correct for bromide ions?
(1)
A a white precipitate forms that dissolves in
concentrated ammonia only
B a white precipitate forms that dissolves in both dilute
and concentrated ammonia
C a cream precipitate forms that dissolves in
concentrated ammonia only
D a cream precipitate forms that dissolves in both dilute
and concentrated ammonia
(ii) Give a reason why the silver nitrate must be acidified. (1)
