You are trying to separate calcium ions (Ca2+) from lead ions (Pb2+), both present in a mixture and each at a concentration of 0.010 M. You will accomplish this by titrating (adding slowly) sodium sulfate (Na2SO4). (Ksp for CaSO4 = 4.9 x 10^-5; Ksp for PbSO4 = 1.3 x 10^-8 at 25 degrees C). a. Which will be the first salt to precipitate b. What will be the concentration of the first ion to precipitate (Ca2+ or Pb2+) be when the second salt begins to precipitate?
