Question
**Titration of Lactic Acid with Sodium Hydroxide**

*Overview:*
Titus conducts a titration experiment involving 45 mL of 0.750 M lactic acid (HC₃H₅O₃) with a known acid dissociation constant (Ka) of 1.5 × 10⁻⁴, using a 0.250 M sodium hydroxide (NaOH) solution.

*Objective:*
Calculate the pH of the resulting solution at each specified point during the titration process.

*Points of Interest:*

1. **After adding 24.750000000000004 mL of the NaOH solution:**  
   - [pH calculation required here]

2. **At the equivalence point:**  
   - [pH calculation required here]

3. **After adding 191 mL of the NaOH solution:**  
   - [pH calculation required here]

*Instructions for Calculation:*  
Assess and provide the pH values at each of the specified points during the titration by considering the stoichiometry of the reaction and the properties of the acid-base pair involved.
