pH
a basic solution:
[tex]\tt [H^+]=10^{-11.2}=6.3\times 10^{-12}[/tex]
an acidic solution:
[tex]\tt [H^+]=10^{-2.4}=3.9\times 10^{-3}[/tex]
the approximate difference:
[tex]\tt =3.9\times 10^{-3}-6.3\times 10^{-12}=3.8999\times 10^{-3}[/tex]
the difference between the two is almost the same as the acid concentration value because the base concentration value is very small
