Cation tests
white precipitate
Aluminium
NH3
doesn't dissolve in excess ammonia
NaOH
dissolves in excess
Lead
NH3
doesn't dissolve in excess ammonia
NaOH
dissolves in excess
Zinc
NH3
dissolves in excess
NaOH
dissolves in excess
Calcium
Nh3
no precipitate is formed
NaOH
doesn't dissolve in excess
colourful precipitates
Copper (Cu2+)
NH3
forms a light blue precipitate
dissolves in excess to form a deep blue solution
NaOH
forms a light blue precipitate
doesn't dissolve in excess
Iron (II) (Fe2+)
NH3
forms a green precipitate
doesn't dissolve in excess
NaOH
forms a green precipitate
doesn't dissolve in excess
Iron (III) (Fe3+)
NH3
forms a reddish brown precipitate
doesn't dissolve in excess
NaOH

Anion Tests
test for anions
Carbonate (CO3 2-)
test
add dilute acid to substance
if effervescence is seen
test for carbon dioxide
buble the gas through limewater
if a white precipitate is formed, CO3 2- ions are present
Chloride (Cl-)
test
acidify with dilute nitric acid, then add AgNo3 (aq) OR PbNO3
result
white ppt of AgCl is formed
Iodide (I-)
test
acidify with dilute nitric acid, then add AgNo3 (aq) OR PbNO3
result
yellow ppt of AgI formed
ppt of lead(II) iodide is formed
nitrate (NO3 2-)
test
make solution alkaline with aqueous sodium hydroxide then add aluminium foil; and warm carefully
result
ammonia gas given off
test for ammonia gas
place moist red litmus paper at the mouth of the test tube
if it turns blue, ammonia is present
Sulfate (SO4 2-)
test
Acidify with dilute HCl, then add BaCl (aq) or BaNO3 (aq)
result
white ppt of barium sulfate is formed
