The pH scale is a measure of the acidity of an aqueous solution. The acidity is the concentration of hydrogen ion H+, [H+].
pH is defined as -log10[H+] and this can be rearranged to pH= log10(1/[H+])
pH is a logarithmic measure. Look at the following for solutions of HCl a strong acid.
0.1M, pH 1
0.01 M pH 2
0.001M pH 3
pH7 is neutral. This is because in pure water there is an equilibrium
H2O<-> H+ + OH-
Under standard conditions the concentration of H+ in pure water is 10-7 M or (1/107)M. Taking logarithms and applying the definition pH 7 is the result.
