8 Overview Physical and Inorganic Chemistry Component 1 PI1.1 Redox and standard electrode potential The ideas of reduction and oxidation. Produce and use ion/electron half-equations. Half-cells and how they can be used to produce electrochemical cells. Standard electrode potentials to calculate EMF values. Apply these principles to the hydrogen fuel cell and balance its advantages and disadvantages. p10 PI1.2 Redox reactions Recall and use common ion/electron half-equations. Combine half-equations to give an overall redox equation. Practical techniques of titration with redox reactions. Analyse the copper content of solutions using indirect redox titrations. p19 PI3 Chemical kinetics Measuring reaction rates, including sampling and quenching. Using experimental data to find reaction orders and rate equations. Rate-determining steps and reaction mechanism. The link between temperature, activation energy and rate using the Arrhenius equation. p49 PI2.1 Chemistry of the p-block The pattern in metallic character on going down groups and its effect on bonding and acid-base character of compounds. The inert pair effect and its effect on the redox properties of compounds. The ideas of electron deficiency and octet expansion to explain compounds with different numbers of electrons in their outer shells. The bonding in donor-acceptor compounds and Al 2 Cl 6 . The reactions of group 4 chlorides with water. The reactions of chlorine with sodium hydroxide. The reactions of concentrated sulfuric acid with sodium halides. p27 PI2.2 Chemistry of the d-block transition metals Variable oxidation states in the d-block elements. The bonding in tetrahedral and octahedral complexes. The origin of colour in complexes. Examples of complexes containing copper (II) and cobalt (II). The catalytic properties of transition metals and their compounds. The aqueous reactions of sodium hydroxide with Cr 3+ , Fe 2+ , Fe 3+ and Cu 2+ . p39
