**Titration of Hydrochloric Acid with Sodium Hydroxide**

This experiment involves titrating 100 mL of a 0.200 M hydrochloric acid (HCl) solution with a 0.250 M sodium hydroxide (NaOH) solution. 

**Objective:**

The purpose of this titration is to determine the amount of NaOH solution required to completely neutralize the HCl solution.

**Method:**

- Measure 100 mL of 0.200 M HCl solution.
- Gradually add 0.250 M NaOH solution while continuously stirring the mixture.
- Monitor the pH change to detect the endpoint, where the number of moles of NaOH equals the number of moles of HCl.

**Note:**

No graphs or diagrams are provided in this text.
