    Oxidising species in the following reaction is\[Zn(s)+C{{u}^{2+}}(aq)\xrightarrow{{}}Z{{n}^{2+}}(aq)+cu\]

    A)  Zn                                         

    B)  \[C{{u}^{2+}}\]

    C)  \[Z{{n}^{2+}}\]                                

    D)  Cu

    Correct Answer: A

    Solution :

                     \[Zn\,(s)+C{{u}^{2+}}(aq)\xrightarrow{{}}Z{{n}^{2+}}(aq)+Cu\]Oxidation is a process in which loss of electrons takes place. In this reaction, Zn is oxidised to \[Z{{n}^{2+}}\] hence Zn is the oxidizing species.
