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

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