Rules
-
- All Carbonates Co3^- is insoluble (except group 1 and NH4^+ compounds)
- All metal oxides are insoluble(exc group1 and NH4^+ compounds)
- All Nitrates No^3- is soluble
- All hydroxides are insoluble (exc group 1 and NH4^+ compounds)
- All sulphates So4^- are soluble (except Barium,Calcium and Lead)
- All halides are soluble (except Silver and Lead)
Qualitative analysis
Test for Carbon
- Pour lime water into a test tube which is clear.
- When it bubbles, It becomes cloudy
Test for Chlorine
- Use Blue litmus paper into Cl which becomes white
- Dampen litmus paper and place into gas
Test for Hydrogen
- Burning splint into HCl
- Make a popping noise
Test for Ammonia
- Turns litmus paper from red to blue
Test for Oxygen
- Light a splint and blow it
- Glowing splint will relight in presence of oxygen
-
Test for Anions
- NO^3- -> Alkali/Al foil/Warm/Gas = red litmus -> blue
- SO4^1- -> BaCl2,Ba(No^3)2 = white ppt
