# A student prepares an aqueous solution of a weak monoprotic acid, \(\text{HA(aq)}\). The particulate diagram below represents a sample of the solution after chemical equilibrium is established. Water molecules are omitted for clarity.

Based on the representation, what is the percent ionization of \(\text{HA}\) in this solution?

![A square container representing an aqueous solution. A legend at the top specifies three species: a neutral HA molecule represented by a large gray circle bonded to a small open circle; an A- anion represented by a large gray circle with a minus sign; an H+ cation represented by a small open circle with a plus sign. Inside the container, there are exactly 8 HA molecules, exactly 2 A- anions, and exactly 2 H+ cations evenly dispersed throughout the space. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787143181-k4sHN8.jpg)
