# Problem: A 1.0 L buffer solution is 0.12 M in HNO2 and 0.060 M in KNO2. Which action destroys the buffer?a. adding 0.060 mol of KNO2b. adding 0.060 mol of KOHc. adding 0.060 mol of HNO3d. none of the above

###### FREE Expert Solution

The maximum buffering capacity of a solution is when the pH of the solution is equal to pKa and the buffer range of a solution is pH = pKa ± 1

maximum buffering capacity:              pH = pKa
buffering range:              pH = pKa ± 1

Recall the Henderson-Hasselbalch equation:
