Question
**Problem Statement:**

Determine the pH of a solution that is 0.25 M CH\(_3\)COOH and 0.15 M CH\(_3\)COONa. Be sure your answer has the correct number of significant figures.

*Note:* Reference the \(K_a\) of acids at 25 °C table for additional information.

**Input Section:**

pH = [   ]

- This section includes an interactive input box where users can enter their calculated value of the pH.

Additional tools in the input section include:
- A check box for scientific notation (\( \times 10^{x} \)).
- A reset button (circular arrow) which allows users to clear their input.
- A cancel button (X) to disregard any changes made.
