Which results in a buffered solution?
A) A solution containing a strong acid and its conjugate base
B) A solution containing a strong base and its conjugate acid
C) A solution containing a catalyst
D) A solution containing two organic liquids
E) A solution containing a weak acid and its conjugate base

Question

Quizplus · Accepted Answer

A buffered solution is one that resists changes in pH when small amounts of acid or base are added. This is achieved by having both a weak acid and its conjugate base in the solution, or a weak base and its conjugate acid. Option E describes a solution containing a weak acid and its conjugate base, which is the definition of a buffered solution. The other options do not meet this definition.
