Explain disproportionation reactions of chlorine in water and alkali.

In the subtopic Halide ions and uses of chlorine, this AQA A-Level Chemistry 7405 learning objective focuses on explain disproportionation reactions of chlorine in water and alkali. It belongs to Group 7(17), the halogens, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include chlorine, disproportionation. Disproportionation reaction. means a reaction in which a single substance is both oxidized and reduced, resulting in the formation of two different products Avoid the mistake of students often confuse disproportionation reactions with simple redox reactions, failing to recognize that in disproportionation, the same element is both oxidized and reduced; instead, to clarify, remember that in a disproportionation reaction, such as chlorine reacting with water, chlorine is oxidized to form chloride ions and reduced to form hypochlorous acid. Write the half-equations to show the oxidation and reduction processes clearly For exam answers, when explaining disproportionation reactions of chlorine, remember that chlorine reacts with water to form hydrochloric acid and hypochlorous acid. Write the balanced equation to illustrate this
