Determine the hydroxide ion concentration in a solution that is 0.0033 m hno3. answer in units of m.

Answer is: the hydroxide ion concentration is 3.03·10⁻¹² M.

Chemical dissociation of nitric acid in water: HNO ₃ (aq) → H⁺ (aq) + NO₃⁻ (aq).

c (HNO₃) = [H⁺] = 0.0033 M, because nitric acid is strong acid, nitric acid ionize completely so it percent ionization is 100 %.

[H⁺] · [OH⁻] = 10⁻¹⁴ M².

[OH⁻] = 10⁻¹⁴ M² : 0.0033 M.

[OH⁻] = 3.03·10⁻¹² M.
