a buffer is a solution that has a Weak acid in equlibirum with its conjugate base. So can a buffer solution has a weak base in equlibirum with its conjugate acid? So basically, to create a buffer, you can mix a weak acid with its conj. base OR a weak acid + strong base OR a weak base with a strong acid? Am i Correct?

A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. When strong acids or strong bases are added, buffers either accept protons when they are in excess or donate protons when they have been depleted to minimize changes in pH. Which of the statements correctly describe the properties of a buffer? Select one or more: a. The weak base of an alkaline buffer will...
