Hydrosulfuric acid is a diprotic acid, for which Ka₁ = ? and Ka₂ = ? Determine the concentration of sulfide ion in a 0.10 M hydrosulfuric solution.
a) Ka₁ = 1.0 x 10⁻⁷, Ka₂ = 1.3 x 10⁻⁸, [S²⁻] = 2.35 x 10⁻⁵ M
b) Ka₁ = 1.3 x 10⁻⁸, Ka₂ = 1.0 x 10⁻⁷, [S²⁻] = 3.46 x 10⁻⁶ M
c) Ka₁ = 1.0 x 10⁻⁷, Ka₂ = 1.3 x 10⁻⁸, [S²⁻] = 1.73 x 10⁻⁵ M
d) Ka₁ = 1.3 x 10⁻⁸, Ka₂ = 1.0 x 10⁻⁷, [S²⁻] = 1.35 x 10⁻⁵ M
