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)
