Calculate the pH of 0.2 M NaOH

Calculate the pH of 0.2 M NaOH

NaOH is a strong base, so [OH-] is the same as the concentration of the NaOH itself (it dissolves 100%).
pOH = -log[OH-]
and then pH = 14 – pOH.
The answer is 13.3

    I must inform you, that if I already knew how to do this, I would have clicked on the video. Will not be watching any more of your videos because the last thing I need while studying is being told "you should already know something that you don’t know". Thanks, guy.
