1) When a 50.0-mL solution of 0.20 M NaBr is added to 50.0 mL of 0.20 M Pb(NO3)2 solution, a precipitate of PbBr2 is formed. (a) How many grams of PbBr2 precipitate are produced? (b) Determine the equilibrium concentrations of Na+, Pb2+, Br-, and NO3- ions, respectively, in the saturated solution. (PbBr2 has Ksp = 4.6 x 10-6) 2 ) Given that: Al(OH)3(s) ? Al+(aq) + 3 OH-(aq); Ksp = 4.6 x 10-23 Mg(OH)2(s) ? Mg2+(aq) + 2 OH-(aq); Ksp = 1.8 x 10-11 Carry out a calculation that would show only Al(OH)3, but not Mg(OH)2, will form precipitate in a solution that contain 0.10 M Al3+ and 0.10 M Mg2+ if the solution is buffered at pH = 9.00.
