Question

The concentration of H2S in a saturated aqueous solution at room temperature is approximately 0.1 M. Calculate [H3 O+], [HS−], and [S2−] in the solution:
H2 S(aq) + H2 O(l) ⇌ H3 O+(aq) + HS−(aq)               Ka1 = 8.9 × 10−8
HS−(aq) + H2 O(l) ⇌ H3 O+(aq) + S2−(aq)              Ka2 = 1.0 × 10−19
