2 What is the correct cell notation for a voltaic cell based

2. What is the correct cell notation for a voltaic cell based on the reaction below? Ag, (aq) + Sn (s) Ag (s) + Sn\"(aq) a) Ag (s)|Ag. (aq)Sn2. (aq)| Sn (s) b) Sn (s)Ag+ (aq)Sn2. (aq)| Ag (s) c) Ag (aq)|Ag (s)|| Sn (s)Sn2 (aq) d) Sn (s)[Sn2. (aq)Ag (aq)|Ag(s) e) Ag (s)/Sn2 (aq)l|Ag (aq)|Sn (s) Write a balanced chemical equation for the overall reaction represented by the cell notation below. 3. Pt | H: (g) | H (aq) IISO. (aq) | PbSO.(s) | Pb (s) a) Pt (s) + H2 (g)-H+ (aq) SOF (aq) + Pbso. (s) + Pb (s) b) PbSO. (s) + H2 (g) Pb(s) + 2 H.(aq) + SO42-(aq) c) SOA (aq) + PbSO4 (s) + Pb (s) Pt (s) + H2 (g) + H\' (aq) d) Pb (s) + 2 H\' (aq) + SOA (aq) PbSO.(s) + H2(g) e) None of the above

Solution

2)
here,
Sn oxidises to Sn+2
so, it must be at anode

and at cathode
Ag+ reduces to Ag

in cell notation first we write the oxidation part than reduction part
so, cell notation is
Sn/Sn+2//Ag+/Ag

Answer : option d
