Is it safe to stir \[1\,M\,AgN{{O}_{3}}\] solution with copper spoon? Given:\[E{}^\circ A{{g}^{+}}/Ag=0.80\,V;\] \[{{E}^{o}}\,C{{u}^{2+}}/Cu=0.34\,\text{V}\].

Answer:

                No, it is not feasible. Since copper is a stronger reducing agent than silver, the redox reaction will X immediately take place \[Cu(s)+2A{{g}^{+}}(aq)\xrightarrow{{}}\,C{{u}^{2+}}(aq)\,+2Ag.\]
