This unit requires Physical Chemistry to have been completed.
- Group I: physical properties, storage, reaction with water, air and alcohol, reactivity trends, physical properties of salts, thermal stabilities of nitrates, carbonates and hydrogen carbonates, hydrolysis of carbonates.
- Group II: consideration of properties in comparison with Group 1
- Group VII: physical properties, reactivity trends and comparison with Gp 1, displacement reactions, disproportionation reactions of chlorine, properties of hydrogen halides, tests for halide ions using silver nitrate.
- Trends across the periodic table: consideration of the third period, atomic radius and ionisation energies, properties of oxides, hydroxides and chlorides.
- Group IV: trend in atomic size and ionisation energy, change from non-metal to metal, consideration of oxides (except Pb3O4)and chlorides.
- Transition Metals: the distinction between these and d-block metals, major characteristics and examples (paramagnetism, coloured complex ions, variable oxidation state, catalytic ability), comparison with s and p block elements.
- Acids and bases: historical ideas, Arrhenius’ theory, pH scale, calculation of pH, buffer solutions, acid/base indicators, Bronsted-Lowry theory.
