WebApr 30, 2014 · You can calculate pH if you know the concentration of the NaOH. 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.
