The Henderson-Hasselbach Equation, Used to Calculate the PH of Simple

question 93

Multiple Choice

The Henderson-Hasselbach equation, used to calculate the pH of simple conjugate-pair buffer systems, would be expressed for an ammonia/ammonium chloride buffer, for which Kb(NH₃) is 1.8 × 10^-5, as:

• A) pH = 4.74 + log([NH₃]/[NH₄⁺])
• B) pH = 4.74 + log([NH₄⁺]/[NH₃])
• C) pH = 9.25 + log([NH₃]/[NH₄⁺])
• D) pH = 9.25 + log([NH₄⁺]/[NH₃])
• E) pH = 14.0 - log(1.8 × 10^-5)
