The pH is the negative log of [H+].
pH is -log[H+] and can be found using pH meter.
You usually calculate it with a pH stick. Good question!!.
Sodium chloride solution is neutral.
This is the concentration of the ion H+.
-log[H+] = pH therefore -log[0.001] = 3.00 The pH of a solution of 0.001 mol dm HC1? is 3.00
pH= -log = 1.59
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
The molar concentration of the hydrogen ions
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
pH = -log10[H+], where [H+] is the hydrogen ion concentration. So, in this case, pH = -log10[1], yielding pH = 0.
