I don’t fully understand this question and was looking for an in-depth solution..
A solution is prepared by adding some solid Pblz to water and allowing the solid to come to equilibrium with the solution. The equilibriumconstant for the reaction below is Kc = 7.9×10’9. Pbl2(s) : Pb2+(aq) + 2 i-(aq)What is the equilibrium concentration of sz” in the solution? Assume that some of the solid remains undissolved. Give your answer in moles per litre, accurate to two signiﬁcant ﬁgures. Do not include units as part of your answer. (Enter1.23×10-5 as 1.23e—5.) Number
