Solution: The drawing represents a buffer composed of equal concentrations of a weak acid, HX, and its conjugate base, X-. The heights of the columns are proportional to the concentrations of the components of the buffer.Which of the three drawings (1), (2), (3) represents the buffer after the addition of a strong acid?

Problem

The drawing A bar chart shows HA and A- concentration equal.  Three other charts show: 1) HA decreased, A- increased 2) HA and A- equal, both decreased to the same level 3) HA increased, A- decreased represents a buffer composed of equal concentrations of a weak acid, HX, and its conjugate base, X-. The heights of the columns are proportional to the concentrations of the components of the buffer.

Which of the three drawings (1), (2), (3) represents the buffer after the addition of a strong acid?
