Oxidation state trends . . .
Looks at the increasing tendency towards an oxidation state of +2 as you go down the Group.
Group 4 chlorides . . .
Describes and explains the differences between the chlorides of carbon, silicon and lead as required by UK A level chemistry syllabuses.
Group 4 oxides . . .
Describes and explains the differences between the dioxides of carbon and silicon, and looks at the trend in acid-base behaviour of the oxides as you go down the Group.
Some chemistry of aqueous lead(II) ions . . .
Describes the reactions of lead(II) ions in solution with hydroxide ions, chloride ions, iodide ions and sulphate ions.
