Given the cell Ag `AgCl(s)|NaCl(0.05M)||AgNO_(3)(0.30)|Ag`
(a) write half reaction occurring at the anode. (b). Write half reaction occurring at the cathode.
(c). Write the net ionic equation of te reaction. (d). Calculate `E_(cell)^(0)` at `25^(@)C`
(e). Does the cell reaction go spontaneous as written? (given `E_(AgCl,Cl)^(@)=+0.22"volt"),E_(Ag^(+)//Ag)^(0)=+0.80"volt")`

Call

(a). LHS electrode is anode and half reduction.
`Ag^(+)+Cl^(-)toAgCl(s)+e^(-)` ..(i)
(b) RHS electrode is cathode and half reaction is reduction
`Ag+etoAg(s)` ..(ii)
(c) from equation (i) and (ii) cell reaction is : `Cl^(-)(0.05M)+Ag^(+)(0.30M)toAgCl(S)`
(d). `E_(cell)^(@)=E_(right)^(@)-E_("left")^(@)`
`=(0.80-0.22"volt"=0.58"volt")`
(e). Yes, the e.m.f. value is positive, the reaction will be spontaneous as written in the cell reaction.

Consider the cell `Ag|AgBr(s)|Cr^(-)||Cl^(-)|AgCl(s)|Ag` at `25^(@)C` the solubility product constants of `AgBr` & `AgCl` are respectively `5xx10^(-13

Correct Answer - `[Br^(-)]:[Cl^(-)]=1:200` If cell is taken to be conc, cell `E_(cell)^(@)=0` Anode: `AgtoAg_(a)^(+)+e^(-)` cathode: `underline(Ag_(c)^(+)+e^(-)toAg)` `AghArrAg_(a)^(+)` From nearest Eq, `E_(cell)=E_(cell)^(@)-(0.059)/(1)log(([Ag^(+)]_(a))/([Ag^(+)]_(c)))implies0=0-(0.059)/(1)log(([Ag^(+)]_(a))/([Ag^(+)]_(c)))` `therefore[Ag^(+)]_(a)=[Ag^(+)]_(c)implies(K_(sp)" of " AgBr)/([Br^(-)])=(K_(sp)" of " AgCl)/([Cl^(-)])` or, `(5xx10^(-13))/(10^(-10))=([Br^(-)])/([Cl^(-)])=([Br^(-)])/([Cl^(-)])=(1)/(200)`
