Calculate pH, [H₃O⁺], and [OH^–] for a solution that is 0.026 M HCl and 0.018 M HBr.

• A. [H₃O⁺] = 0.018 M
  [OH^–] = 5.6 × 10^–14 M
  pH = 1.74
• B. [H₃O⁺] = 0.026 M
  [OH^–] = 3.8 × 10^–14 M
  pH = 1.58
• C. [H₃O⁺] = 0.008 M
  [OH^–] = 1.3 × 10^–12 M
  pH = 2.09
• D. [H₃O⁺] = 0.044 M
  [OH^–] = 2.3 × 10^–13 M
  pH = 1.36
