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
