Answer 1

To determine which solution is a base, we need to know that bases typically have a pH greater than 7, while acids have a pH less than 7. A pH of 7 is considered neutral.

Looking at the given solutions:

• Solution A: pH 2 (acidic)
• Solution B: pH 5 (acidic)
• Solution C: pH 7 (neutral)
• Solution D: pH 9 (basic)

Based on this information, the solution that should be identified as being a base is Solution D.
