A cell was constructed with two lead electrodes. The electrolyte in one compartment is 1.0 m Pb(NO₃)₂(aq). In the other compartment, NaI has been added to a Pb(NO₃)₂ solution until a yellow precipitate forms and the concentration of I^– ions is 0.050 mol · L^–1. The potential of this cell is +0.155 V at 298 K.

(a) Calculate the concentration of Pb⁺ ions in the second compartment.

(b) Calculate the solubility product of PbI^–.
