The addition of HF and ________ to water produces a buffer solution. A)HBr B)KNO₃ C)KOH D)NaCl E)NaBr

Question

Quizplus · Accepted Answer

When HF is added to water, it partially dissociates to form H+ and F- ions. However, F- ions react with water to form HF and OH- ions, effectively removing H+ ions from the solution. This creates a buffer solution with a relatively constant pH. In order to establish a buffer solution, the addition of a strong base, such as KOH, would be necessary to react with any excess H+ ions. Therefore, choice C (KOH) is the best option for producing a buffer solution along with HF.
