Question: A solution of Na2SO4 is added drop wise to a solution that is 0.010 M in Ba2+ and 0.010 M in Sr2+. (a) What concentration

A solution of Na2SO4 is added drop wise to a solution that is 0.010 M in Ba2+ and 0.010 M in Sr2+.
(a) What concentration of SO42- is necessary to begin precipitation? (Neglect volume changes. BaSO4 ksp = 1.1 x 10 -10 SrSO4:)
(b) Which cation precipitates first?
(c) What is the concentration of SO42- when the second cation begins to precipitate?
