Answer: Oxidation reaction: [tex]Al(s)\rightarrow Al^{3+}(aq)+3e^-[/tex]
Reduction reaction: [tex]Sn^{2+}(aq)+2e^-\rightarrow Sn(s)[/tex]
Overall redox reaction : [tex]2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)[/tex]
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
[tex]Al(s)\rightarrow Al^{3+}(aq)+3e^-[/tex]
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
[tex]Sn^{2+}(aq)+2e^-\rightarrow Sn(s)[/tex]
Overall redox reaction : [tex]2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)[/tex]
