how much Sr2+ will precipitate if 10^-3 mole Na2SO4 added per litter of solution. How much SO42- and Sr2+ remain after precipitation. Given that 10-4 mole/L of Sr2+ and 10-4 of SO42- are originally present and that pKso = 7.8 for SrSO4 (s)
Homework Answers
given after addition of Na2SO4
total [SO4^2-] in solution = 10^-4 M x + 10^-3 M = 1.1 x 10^-3 M
pKso = -log[Kso] = 7.8
Kso = 1.6 x 10^-8
Kso = [Sr2+][SO4^2-]
at the total [SO4^2-] concentration, calculate [Sr2+] in solution,
[Sr2+] = Kso/[SO4^2-]
= 1.6 x 10^-8/1.1 x 10^-3
= 1.45 x 10^-5 M
So,
[Sr2+] precipitated = 10^-4 - 1.45 x 10^-5 = 8.55 x 10^-5 M
and,
[Sr2+] remained after precipitation = 1.45 x 10^-5 M
[SO4^2-] remained after presipitation = 1.1 x 10^-3 -1.45 x 10^-5 = 1.0855 x 10^-3 M
