12.3 Reactions of Halide Ions Introduction to halide ions, X⁻ The halogens are typical non-metals, they: form singly charge negative ions, X⁻. form ionic compounds with metals and covalent compounds with non-metals. Preparation of halogens in the...
12.4 Uses of Halogens Chlorine is used in the chlorination of water to kill bacteria. The chlorine undergoes disproportionation Cl2(aq) + H2O(l) → HCl(aq) + HClO(aq) Chloric(I) acid, HClO produced decomposes slowly to produce reactive oxygen atoms that kill...
12.12Reactions of Group VII Elements Halogens as oxidising agent Halogens are powerful oxidising agents. However, the oxidising ability decreases down the Therefore, F2 is the most powerful oxidising agent while I2 is the weakest. This is reflected in their ability...
12.1 Physical Properties of Group VII Elements Introduction to Group VII elements Group VII elements(also called the 'halogens') are p-block elements with a characteristic outer shell configuration of ns²np⁵. Some common physical properties of the halogens...
CHAPTER 12: Group VII Physical Properties of Group VII Elements Reactions of Group VII Elements Reactions of Halide Ions Uses of Halogens Learning outcomes: describe the colours of, and the trend in volatility of chlorine, bromine and iodine interpret the...
