Establish the Ka expression of the dissolution of hypochlorous acid (HOCl) and determine the pH using an ICE chart
We will solve this problem through these steps:
Step 1: Write an equation for the dissociation of HOCl
Step 2: Write an expression for the Ka.
Step 3: Set up an ICE table to calculate the H3O+ ion concentration.
Calculate the pH of a 0.400 M solution of hypochlorous acid, for which the Ka value is 2.90 x 10-8. Enter your answer with two decimal places.
