Explain the action of phenolphthalein indicator in the titration of acetic acid, sodium hydroxide

Explanation

**Step-by-Step Solution:**

1. **Identify the Reactants:**
- In this titration, we are using acetic acid (CH₃COOH), which is a weak acid, and sodium hydroxide (NaOH), which is a strong base.

2. **Understand the pH of the Reactants:**
- Acetic acid has a pH generally greater than 6, indicating it is a weak acid. Sodium hydroxide, being a strong base, has a high pH (typically around 13).
