You can calculate pH if you know the concentration of the NaOH.


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.

Since pH + pOH = 14

We can calculate the pH to be 13.

This assumption we made about the base can only be used for strong bases which dissociate completely in water.

Hope this helps!
