Question

calculate the pH of 0.01 m solutions. of sodium hydroxide
​

Answer 1

Na+ ions and OH- ions in Sodium hydroxide (NaOH) will dissociate completely since it is a strong base.

It is given that NaOH solution has concentration of 0.01 M.

We know that,

pH + pOH is always equal to 14 for any solution.

pOH = -log (M of OH-)

pOH = -log(0.01) = - (-2) = 2

Therefore,

pH = 14-2 = 12

Answer:

pH of the given sodium hydroxide solution is 12.
