Question
What is always a characteristic of a solution that contains a buffer?
Solution
A solution that contains a buffer always has the characteristic of resisting changes in pH. This means that if an acid or base is added to the solution, the buffer will react with it to prevent the pH of the solution from changing significantly. This is because a buffer is made up of a weak acid and its conjugate base, or a weak base and its conjugate acid. When an acid is added, the base component of the buffer will react with it, and when a base is added, the acid component of the buffer will react with it. This allows the buffer to maintain a relatively constant pH.
