Use the "My solution mode" simulation to complete the activity.

Question

Acid-Base Solutions

How could you adjust the settings of the simulation to increase the number of red ( H3O+ ) and blue ( A− ) particles in the solution? In one to two sentences, describe your answer and explain how and why this would change the pH of the solution.

Answer 1

To increase the number of red (H₃O⁺) and blue (A⁻) particles in the solution, you could adjust the settings by increasing the concentration of an acid, which would dissociate to produce more H₃O⁺ ions, and adding a conjugate base, which would introduce more A⁻ ions. This would lower the pH of the solution since a higher concentration of H₃O⁺ ions corresponds to increased acidity, resulting in a lower pH value.
