**Question**: What is the pH after the addition of 50.0 mL KOH?**Response Box**: - **pH =** 9.68 **Feedback**: Incorrect---The image is a part of an online educational exercise where the user is prompted to calculate and input the pH value after adding 50.0 mL of KOH (potassium hydroxide). The pH calculated by the user is 9.68, but this response is marked as "Incorrect." This setup indicates that understanding the correct calculation of pH with the addition of a base is necessary for mastering this concept. **Title: Calculating pH in Titration Process of HClO with KOH****Objective:**Calculate the pH for each stage in the titration of 50.0 mL of 0.180 M HClO (aqueous) with 0.180 M KOH (aqueous). Use the ionization constant for HClO.---This section will guide you through the process of calculating the pH at different points in the titration of hypochlorous acid (HClO) with potassium hydroxide (KOH). In this example, both the reactants have a concentration of 0.180 M. The following key concepts and steps will be covered:1. **Understanding Titration:** - Definition of titration - Purpose of using titration in chemical reactions2. **Components Involved:** - Characteristics of hypochlorous acid (HClO) - Characteristics of potassium hydroxide (KOH)3. **Calculation Methodologies:** - Initial pH calculation using the ionization constant of HClO - pH calculation at the equivalence point - Buffer region analysis - Post-equivalence point pH determination4. **Ionization Constant:** - Explanation of the ionization constant and its role in acid-base reactions - Application of the constant in calculationsBy understanding these fundamental elements and calculations, students will be able to determine the pH changes throughout the titration process effectively.

The question is based on the concept of the pH of the solution.It is defined as a negative logarithm of hydrogen ion concentration present in a solution.NOTE: please note as pKa value is not provided, I have used standard value.If your question SPECIFICALLY asks you to use some particular value, please use that otherwise it will show INCORRECT solution.first step, we calculate moles of acid by multiplying molarity with volume.All acid react with base to form corresponding salt at equivalence point.We calculate equivalent volume of base added based on standard molarity equation.Moles of salt are equal to moles of acid based on reaction stoichiometry.Concentration salt is obtained by dividing moles of salt with total volume of the solution.As Salt is of weak acid and strong base, therefore undergoes alkaline hydrolysis.We use formula formula of weak acid and strong base salt to calculate PH.Thus, pH is found to be 10.21
