🤓 Based on our data, we think this question is relevant for Professor Lewis' class at USF.

# Solution: A 250.0 mL solution of 0.100 M HClO is titrated with 0.200 M NaOH. What is the expected pH of the resulting solution once 50.0 mL of the NaOH solution has been added to the HClO solution?A. 4.68B. 7.36C. 7.71D. 8.20E. 13.30

###### Problem

A 250.0 mL solution of 0.100 M HClO is titrated with 0.200 M NaOH. What is the expected pH of the resulting solution once 50.0 mL of the NaOH solution has been added to the HClO solution?

A. 4.68

B. 7.36

C. 7.71

D. 8.20

E. 13.30

###### Solution

We are being asked to determine the pH of the HClO solution when 50.0 mL of NaOH solution is added to it.

We will calculate the pH of the HClO solution using the following steps:

Step 1. Calculate the initial amounts of HClO and NaOH in moles before the reaction happens.

Step 2. Write the chemical equation for the reaction between HClO and NaOH.

Step 3. Construct an ICF Chart.

Step 4. Calculate pH.

Step 1. Calculate the initial amounts of HClO and NaOH in moles before the reaction happens.

molarity (volume) → moles

Recall:

*convert volumes from mL to L → 1 mL = 10-3 L
