NaOH,being a strong base will dissociate completely in aqueous solution.
NaOH
Na+ + OH-
Here, 1 M of NaOH will give 1 M of Na+ and 1 M of
OH-
Similarly, 0.398 M of NaOH will give 0.398 M of Na+ and 0.398 M of OH-
We know,
pOH = - log [OH-]
pOH = - log(0.398)
pOH = 0.400
We also know,
pOH+ pH = 14
pH = 14 - pOH
pH = 14 - 0.400
pH = 13.6

Calculate the [H3O+] and [OH−] of a sodium hydroxide solution with a pH = 12.00.
A chemist must prepare 750.0 mL of sodium hydroxide solution with a pH of 13.70 at 25 °C. She will do this in three steps: • Fill a 750.0 mL volumetric flask about halfway with distilled water. • Weigh out a small amount of solid sodium hydroxide and add it to the flask. • Fill the flask to the mark with distilled water. Calculate the mass of sodium hydroxide that the chemist must weigh out in the second step. Round...
