The [OH⁻] of the solution : 1 x 10⁻¹¹ M
Given
[H30) : 1 x 10-3 M.
Required
the [OH]
Solution
The water equilibrium constant is a product of the concentrations of [H3O +] and [OH-]
Kw = [H₃O⁺] [OH⁻]
Input the value of [H₃O⁺]
1 x 10⁻¹⁴ = 1 x 10⁻³ x [OH⁻]
[OH⁻] = 1 x 10⁻¹⁴ : 1 x 10⁻³
[OH⁻] = 1 x 10⁻¹¹ M
