S2- concentration in a saturated solution (0.10 M) of H2S
What is the S2- concentration in a saturated solution (0.10 M) of H2S, in which the pH has been adjusted to 6.00 by the addition of HCl? For H2S, Ka1 = 1.1 × 10-7 and Ka2 = 1.0 × 10-14.
A) 1.1 × 10-16 M
B) 1.1 × 10-10 M
C) 1.0 × 10-2 M
D) 3.2 × 10-8 M
--------------------------------------------------
The answer is B) 1.1 × 10-10 M.
