A small amount of solid AgBr was added to a 0.0100 M solution of NaBr, causing it to become saturated with AgBr. A silver electrode was placed in the solution along with a reference electrode, whose electrode potential was 0.246 V. The voltage of the cell was 0.055 V. Calculate the Ksp for AgBr.
Ag+ + e- -> Ag(s)
E^o = 0.800 V
