The Electron Transfer Reactions of Nickel in an Aqueous Solution of CuCl2

The electron transfer reactions of nickel in an aqueous solution of CuCl2 can be studied to understand the nature of metal oxidation and reduction. When a piece of nickel is placed in an aqueous solution of CuCl2, it undergoes oxidation and reduction reactions. The nickel is reduced, meaning that it loses electrons, and the Cu2+ is oxidized, meaning that it gains electrons (Kumar et al., 2019). The electrons that are lost by the nickel will be used to reduce the Cu2+ ions. This type of reaction is known as the redox reaction (González-García et al., 2008). The oxidation and reduction reactions of nickel in an aqueous solution of CuCl2 can be described as follows. The nickel loses two electrons and is oxidized to become Ni2+. The Cu2+ ions gain two electrons and are reduced to become copper metal. This reaction can be expressed as follows: 2Ni (s) + CuCl2 (aq) ? 2Ni2+ (aq) + Cu (s) + 2Cl- (aq) (Kumar et al., 2019). The amount of oxidation and reduction depends on the concentration of the CuCl2 solution. The higher the concentration of the solution, the more electrons are transferred and the greater the oxidation and reduction of the nickel. The reaction rate also depends on the temperature. Higher temperatures will speed up the reaction rate while lower temperatures will slow it down (González-García et al., 2018). Cont…
