3
Q

5
Q
How do you test for halide ions? (Cl, Br, I etc).
What colour is each ppt?
A
- Add Silver nitrate (AgNO3)
- If a halide is present, a precipitate will form.
These precipitates should be white for Chlorides, Cream for bromides and yellow for iodides. - Add dilute ammonia. If the precipitate dissolves, then there are chloride ions. If not, step 4.
- Add concentrated ammonia. If the precipitate dissolves, then bromides are present. If not, then the halide ions are iodides.
6
Q
What does partial disassociation mean?
A
At any time, some of the acid molecules have split up into H+ in and the appropriate anion, but some are still complete.
7
Q
What is the definition of a base?
A
A proton acceptor
8
Q
What is the definition of an acid?
A
A proton donor
9
Q
What is the definition of an alkali?
A
A soluble base that releases OH- ions in water
10
Q
What is the definition of a salt?
A
Salts are ionic compounds formed when the H+ ions in acids are replaced by metal ions or ammonium ions.
