Answer
Explanation:
Step1: Analyze solution A's pH change
As time goes from 0 - 4 seconds, pH of solution A changes from 11.0 to 9.0. Since a lower pH indicates higher acidity and the pH is decreasing, acidity of solution A increases.
Step2: Analyze solution B's pH change
As time goes from 0 - 4 seconds, pH of solution B changes from 8.5 to 5.8. Since a lower pH indicates higher acidity and the pH is decreasing, acidity of solution B increases.
Answer:
The pH of solution A decreases, and the pH of solution B decreases.
