### Post-Lab Question #2: **Question:** What is the pH of the solution obtained by mixing 30.00 mL of 0.250 M HCl and 30.00 mL of 0.125 M NaOH? We assume additive volumes. **Answer Choices:** 1. 1.20 2. 2.38 3. 7.00 4. 10.1 **Explanation:** In this post-lab question, you are asked to calculate the pH of a solution resulting from the mixing of hydrochloric acid (HCl) and sodium hydroxide (NaOH). Both the HCl and NaOH have known volumes and molarities. When these two solutions are mixed, the HCl and NaOH will neutralize each other until one of the reactants is completely consumed. The possible answers to the question are 1.20, 2.38, 7.00, and 10.1. Each represents a potential pH value of the resulting solution.
