The pH of 0.01 ; M ;NaOH (aq) solution will be - Vidyadip

MCQ

The $pH$ of $0.01\; M \;NaOH (aq)$ solution will be

A
$7.01$
B
$2$
✓
$12$
D
$9$

✓

Answer

Correct option: C.

$12$

c
$\mathrm{NaOH}(\mathrm{aq})$ Is strong base solution

$\mathrm{So},\left[\mathrm{OH}^{-}\right]=\mathrm{N}=10^{-2} \mathrm{N}$

$\mathrm{pOH}=-\log \left[\mathrm{OH}^{-}\right]=-\log 10^{-2}=2$

$\mathrm{pH}=14-\mathrm{pOH}=14-2$

$\mathrm{pH}=12$
