✓
Answer
Correct option: B.
strongly acidic
The pH of an aqueous solution is Zero. The solution is strongly acidic.Explanation:
$ \mathrm{pH}=-\log _{10}\left[\mathrm{H}^{+}\right] $
$ \therefore\left[\mathrm{H}^{+}\right]=10^{-\mathrm{pH}} $
$ =10^0 $
$ =1 $
$ {\left[\mathrm{H}^{+}\right]=1 \mathrm{M}} $
The, solution is strongly acidic.
