Question
consider two half cells based on the Rxn
Ag+(aq) +e- ----> Ag(s)
the left half cell contain Ag+ ions at unit concn , &the right half cell initially had the same concn of Ag+ ions , but just enough NaCl (aq) had been added to completely precipitate the Ag+(aq) as AgCl . if emf ofthe cell is 0.29 V , then log10Ksp would have been ?? ( ANS -9.804)

Joshi sir comment
Ecell = EC - EA - (0.0591/1) logs
on taking the values 0.29 = -0.0591 logs
or logs = -0.29/0.0591 = -4.907
now Ksp = s2
so logKsp = 2logs = -9.8
