What is the ph of 1M NaOH

Answer»

NaOH is a strong base, so similarly, it fully DISSOCIATES to Na+ and OH-, therefore 1M NaOH produces 1M of OH-. In this case there are a few WAY to find the pH. The way I always did it is using the assumption that pH + pOH = 14 (this comes from the assumption of the water constant being 10e-14)

Therefore, for NaOH, pOH=-log[OH-] = -log1 = 0 so pH = 14 - pOH = 14 - 0 = 14
