Question

**Buffer Calculation Problem**

A hypochlorous acid buffer is prepared with the following components:
- 0.10 moles of HClO 
- 0.10 moles of ClO⁻

The initial conditions of the solution are described by:
- pH = pKa = 7.40

**Task:** Calculate the pH after the addition of 0.010 moles of HCl. Provide your answer to two decimal places.

**Instructions:** Use your knowledge of buffer systems and the Henderson-Hasselbalch equation to determine the new pH after the change in concentration.

Expert Solution
Step 1

pH = pKa + log[salt]/[acid]

ClO-  +  HCl  ----->  HClO  +   Cl-

Number of moles of HClO formed = number of moles of HCl added
