Calculate the pH, pOH, and the S²−concentration in a 0.10 M H2S solution, given Ka1=1.0×10−7 and Ka2=1.0×10−19
A) pH = 2.00, pOH = 12.00, S²− concentration = 0.10 M
B) pH = 7.00, pOH = 7.00, S²−concentration = 0.05 M
C) pH = 2.00, pOH = 12.00, S²− concentration = 0.05 M
D) pH = 7.00, pOH = 7.00, S²−concentration = 0.10 M
