Given:  Ksp of PbBr2 is 6.60x10-6Part A. Molar solubility of PbBr2 in pure water PbBr2 (s)  ⇌  Pb2+(aq) + 2 Br–(aq)Step 1: ICE Chart[readmore]Step 2: The Ksp expression for PbBr2 is:Ksp = productsreactantsKsp =[Pb2+][Br-]2=6.60×10-6Step 3: The solubility for PbBr2 is:[Pb2+][Br-]2=6.60×10-6[x][2x]2=6.60×10-64x34=6.60×10-64x33 = 6.60×10-643x = 0.0118 MPart B. Molar solubility of PbBr2 in 0.500M KBr solution PbBr2 (s)  ⇌  Pb2+(aq) + 2 Br–(aq)KBr (aq)  ⇌  K+(aq) + Br–(aq)Step 1: ICE ChartStep 2: The Ksp expression for PbBr2 is:Ksp = productsreactantsKsp =[Pb2+][Br-]2=6.60×10-6Step 3: The solubility for PbBr2 is:[Pb2+][Br-]2=6.60×10-6[x][0.500x]2=6.60×10-60.25x30.25=6.60×10-60.25x33 = 6.60×10-60.253x = 0.0298 MPart C. Molar solubility of PbBr2 in a 0.500M Pb(NO3)2 solutionPbBr2 (s)  ⇌  Pb2+(aq) + 2 Br–(aq)Pb(NO3)2 (aq)  ⇌  Pb2+(aq) + NO3–(aq)Step 1: ICE ChartStep 2: The Ksp expression for PbBr2 is:Ksp = productsreactantsKsp =[Pb2+][Br-]2=6.60×10-6Step 3: The solubility for PbBr2 is:[Pb2+][Br-]2=6.60×10-6[0.500][2x]2=6.60×10-62x22=6.60×10-62x2 = 6.60×10-62x = 1.817x10-3 M
