Answer 1

To determine which solution is a base, we can refer to the pH scale. A pH value less than 7 indicates an acidic solution, a pH of 7 indicates a neutral solution, and a pH greater than 7 indicates a basic (alkaline) solution.

Here's the breakdown of the pH values for each solution:

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

Since Solution D has a pH greater than 7, it should be identified as the base.

**Answer: Solution D**
