Question

Calculate the pH of 0.036M NaOH

Answer 1

Answer:

The pH of the solution is 12.56.

Explanation:

Concentration of NaOH= 0.036 M

{tex]NaOH(aq)\rightarrow Na^++OH^-[/tex]

1 mol of NaOH gives 1 mol of hydroxide ions, then 0.036 M of NaOH will give 0.036 M of hydroxide ions.

$[OH^-]=0.036 M$

$pOH=-\log[OH^-]$

$pOH=-\log[0.036] = 1.44$

pH + pOH= 14

pH = 14 - pOH = 12.56

The pH of the solution is 12.56.
