(pKa of HOCl = 7.46)ANSWER 11. Sodium hypochlorite is a common ingredient in household bleach. What is the pH of this bleach if it contains 5% NaOCl by mass? (pKa of HOCl = 7.46) ANSWER 11. Here’s the best way to solve it.Notice, since we have two significant figures for the concentration, we need two decimal places for our pOH. So to find the pH, we know that pH plus pOH is equal to 14.00 at 25 degrees Celsius. So we can plug in the pOH of 2.70, and that gives us pH plus 2.70 is equal to 14.00. So the pH of the solution is equal to 11.30.If the pH value is larger than 7, the solution is called basic or alkaline.
