Answer 1

To identify which solution is a base, we can refer to the pH scale. A pH of 7 is neutral, values below 7 are acidic, and values above 7 are basic (alkaline).

From the given solutions:

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

Therefore, the solution that should be identified as a base is:

Solution D (pH 9).
