Silver can be separated from gold because silver dissolve in nitric acid while gold does not. Is this dissolution of silver in nitric acid and acid-base reaction or an oxidation-reduction reaction? Explain your answer.

Answer:

Yes, it is an redox reaction.

Explanation:

[tex]2Ag_{(aq)} +2HNO_{3}_{(s)} =2AgNO_{3}_{(aq)} +H_{2}_{(g)}[/tex]

In this reaction silver is oxidated to [tex]Ag^{+}[/tex] and [tex]H^{+}[/tex] is reduced to [tex]H_{2}[/tex]

reduction semi reaction

[tex]2H^{+}+2e=H_{2}[/tex]

oxidationsemi reaction

[tex]Ag_{s}=Ag^{+}+e[/tex]

global reaction

[tex]2Ag_{(aq)} +2HNO_{3}_{(s)} =2AgNO_{3}_{(aq)} +H_{2}_{(g)}[/tex]
