A) \[Pt(s)|{{H}_{2}}(g),\]\[1\,\,bar|1\,M\,KCl(aq)|AgCl(s)|Ag(s)\]
B) \[Pt(s)|{{H}_{2}}(g),\]\[1\,\,bar|1\,M\,HCl(aq)|1MA{{g}^{+}}(aq)|Ag(s)\]
C) \[Pt(s)|{{H}_{2}}(g),\]\[1\,\,bar|1\,M\,HCl(aq)|AgCl(s)|Ag(s)\]
D) \[Pt(s)|{{H}_{2}}(g),\]\[1\,\,bar|1\,M\,HCl(aq)|Ag(s)|AgCl(s)\]
Correct Answer: B
Solution :
[b] \[2AgCl(s)+{{H}_{2}}(g)\to 2HCl(aq)+2Ag(s)\] The activities of solids and liquids are taken as unity and at low concentrations, the activity of a solute is approximated to its molarity. The cell reaction will be \[Pt(s)|{{H}_{2}}(g),1bar|{{H}^{+}}(aq)1M|AgCl(aq)1M|Ag(s)\]You need to login to perform this action.
