WebApr 30, 2014 · Explanation: You will need to know the molarity of the NaOH. Let's assume the solution is 0.1M. NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. We can calculate the pH to be 13. http://endmemo.com/chem/compound/na2o2.php
