Chapter 18, Problem 42(choose chapter or problem)
A solution is 0.010 M in both and To this solution, is slowly added. (a) Which anion will precipitate first from solution? 0.50 M Pb1NO3221aq2 SO4 CrO 2-. 4 2- Ag+Pb2+ 1aq2 1aq2 3I-4 PbI2 Ksp = 8.5 * 10-17. PbI2, Ksp = 7.1 * 103Ag -9; +4 = 0.10 M. 3Pb2+4 = Na2CO31aq2? Na2SO41aq2, 0.001 M NaOH1aq2, 0.50 M 3Ba2+ 0.10 M NaCl1aq2, 0.05 M 4 = 3Ca2+4 = 0.050 M: (b) What is at the point at which the second anion begins to precipitate? (c) Are the two anions effectively separated by this fractional precipitation?
