Quizplus · Accepted Answer

A buffer solution is created by combining a weak acid or base with its conjugate. In this case, HCl is a strong acid, but when added to water with NH3, it will react to form NH4+ and Cl-. NH3 is a weak base, and NH4+ is its conjugate acid. Therefore, the addition of HCl and NH3 to water produces a buffer solution. Option B is the only one containing NH3 and NH4+.
