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
$\mathrm{NaOH}(\mathrm{aq})$ Is strong base solution
$\mathrm{So},\left[\mathrm{OH}^{-}\right]=\mathrm{N}=10^{-2} \mathrm{N}$
$\mathrm{pOH}=-\log \left[\mathrm{OH}^{-}\right]=-\log 10^{-2}=2$
$\mathrm{pH}=14-\mathrm{pOH}=14-2$
$\mathrm{pH}=12$
