A) \[Pt({{H}_{2}})|{{H}^{+}}(Ag)\]
B) \[Ag,AgCl|C{{l}^{-}}(aq)\]
C) \[Pt|\]Quinhydrone\[|{{H}^{+}}(aq)\]
D) \[Ag|A{{g}^{+}}(aq)\]
Correct Answer: B
Solution :
\[\frac{1}{2}{{H}_{2}}(g)\to {{H}^{+}}(aq)+{{e}^{-}}\] \[{{E}_{cell}}=E_{cell}^{o}-0.0591\,\,\log \,[{{H}^{+}}]\] \[Ag(s)+C{{l}^{-}}(aq)\to AgCl(s)+{{e}^{-}}\] \[{{E}_{cell}}+E_{cell}^{o}-0.0591\,\,\,\text{log}\,\,1/[C{{l}^{-}}]\] \[{{E}_{cell}}=E_{cell}^{o}-0.0591\log [{{H}^{+}}]\] \[Ag(s)\to A{{g}^{+}}(aq)\] \[{{E}_{cell}}=E_{cell}^{o}-0.0591\log [A{{g}^{+}}]\]You need to login to perform this action.
