Question
**Tutorial: Titration Stoichiometry**

This question will guide you through the steps of calculating the volume of titrant required to reach the endpoint, based on the volume and concentration of analyte.

**Consider the standardization of NaOH by titration with C₆H₈O₇, according to the following chemical reaction:**

\[ 3 \text{NaOH(aq)} + \text{C₆H₈O₇(aq)} \rightarrow \text{Na₃C₆H₅O₇(aq)} + 3 \text{H₂O(l)} \]

**Step 1: Evaluate the question. How many moles of aqueous sodium hydroxide (NaOH) will react to completely neutralize one mole of aqueous citric acid (C₆H₈O₇)?**

Options:
- A) 1
- B) 2
- C) 3
- D) 4
- E) 5

### Explanation

The provided chemical equation indicates that 3 moles of sodium hydroxide (NaOH) are required to react completely with 1 mole of citric acid (C₆H₈O₇) to form sodium citrate (Na₃C₆H₅O₇) and water. The stoichiometry of the reaction is based on the balanced equation.

### Answer

Option C) 3
