know the general rules for predicting the solubility of ionic compounds in water:
- common sodium, potassium and ammonium compounds are soluble
- all nitrates are soluble
- common chlorides are soluble, except those of silver and lead (II)
- common sulfates are soluble, except for those of barium, calcium and lead (II)
- common carbonates are insoluble, except for those of sodium, potassium and ammonium
- common hydroxides are insoluble except for those of sodium, potassium and calcium (calcium hydroxide is slightly soluble).
#2.35
understand acids and bases in terms of proton transfer
#2.36
understand that an acid is a proton donor and a base is a proton acceptor
#2.37
describe the reactions of hydrochloric acid, sulfuric acid and nitric acid with metals, bases and metal carbonates (excluding the reactions between nitric acid and metals) to form salts
#2.38
know that metal oxides, metal hydroxides and ammonia can act as bases, and that alkalis are bases that are soluble in water
#2.39
describe an experiment to prepare a pure, dry sample of a soluble salt, starting from an insoluble reactant
#2.40C
describe an experiment to prepare a pure, dry sample of a soluble salt, starting from an acid and alkali
#2.41C
describe an experiment to prepare a pure, dry sample of an insoluble salt, starting from two soluble reactants
#2.42
practical: prepare a sample of pure, dry hydrated copper (II) sulfate crystals starting from copper (II) oxide
#2.43C
practical: prepare a sample of pure, dry lead (II) sulfate
