Question
**Adjusting pH in an Unbuffered Solution**

A 0.1-L unbuffered solution needs the pH adjusted from 3.5 to 2. How many microliters of a 12 molar HCl solution need to be added to adjust the pH?

**Instructions:**

- Report your answer to four decimal places.
- Assume the volume of HCl being added is negligible and the total volume of the solution does not change.
- The volume of the solution is *not* 1 L as it was in the practice pools.
- The question requests your answer be reported in μL (microliters).

**Media Resource:**

- **Name:** CalculatingChangeInpH (04:33)
- **Duration:** 04:33
