Following four solutions are prepared by
mixing different volumes of NaOH and
HCl of different concentrations, pH of
which one of them will be equal to 1 ?
As we have learnt,
The p(H) scale -
Hydronium ion concentration in molarity is more conveniently expressed on a logarithmic scale known as p(H) scale.
- wherein
The p(H) of a solution is defined as negative logarithm to base 10 of the activity of hydrogen ion
miliequivelent of HCl - miliequivelent of NaOH
Remaining miliequivelent of HCl
15 - 5 = 10
N of remaining HCl
[H+] = 10-1
pH = -log 10-1 = 1
