1
Q
How do you test for chlorides, bromides or iodide ions?
A
Add dilute nitric acid HNO3, followed by silver nitrate solution AgNO3.
2
Q
Most chlorides, bromides and iodides are……
A
aqueous in solution.
3
Q
A chloride ion gives a…..
A
white precipitate of silver chloride.
4
Q
A bromide ion gives a…..
A
cream precipitate of silver bromide.
5
Q
A iodide ion gives a….
A
yellow precipitate of silver iodide.
6
Q
Why do you add nitric acid?
A
Get rid of carbonate or sulfate ions before the test.
7
Q
Why do you always use nitric acid and not hydrochloric acid?
A
HCL contains chloride ions, can interfere and create silver chloride.
8
Q
ions that can not be identified by a precipitate reaction?
A
Nitrates, because all soluble.
