[17][18] Treatment of an arenediazonium salt with CuCl leads to an aryl chloride, for example: The reaction has wide scope and usually gives good yields. For example, consider this reaction, which shows oxidation by the loss of electrons:\r\n\"image4.png\"\r\n\r\nNotice that the zinc metal (the reactant) has an oxidation number of zero (rule 1), and the zinc cation (the product) has an oxidation number of +2 (rule 2). a. BrO_{3} b. P_{4} c. AsO_{4}H_{3} What is the oxidation state of the phosphorous atom in P_4O_10? It is widely used in printing, dyeing, as a wood preservative and in fungicides. SOLVED: The balanced equation between copper (II) chloride and aluminum is: 3CuCl2 (aq) + 2Al (s) 3Cu (s) + 2AlCl3 (aq) Aluminum had an initial oxidation number of zero and lost electrons to become aluminum ion (Al3+) in AlCl3.
