We are being asked to calculate the pH of a solution when 245 mL of a 0.143 M solution of Ba(OH)2 was mixed with 400 mL of 0.53 M acetic acid.


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

Step 1. Write the chemical equation for the reaction between acetic acid and Ba(OH)2.
Step 2. Calculate the initial amounts of acetic acid and Ba(OH)2 in moles before the reaction happens.
Step 3. Construct an ICF Chart.
Step 4. Calculate pH.


Step 1. Write the chemical equation for the reaction between acetic acid and Ba(OH)2.
