• Solution A
• Solution C
• Solution D
• Solution B

Answer 1

To identify a base among the solutions tested by Lila, we need to understand the pH scale. A pH less than 7 indicates an acid, a pH of 7 is neutral, and a pH greater than 7 indicates a base.

Here's the breakdown of the 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, Solution D, with a pH of 9, should be identified as a base.

So the correct answer is:
• Solution D
