In order to express smaller concentrations for acid, neutral and alkaline solutions in a more convenient way, Sorensen in 1909 introduced a new scale which is known as ______ scale.
In order to express smaller concentrations for acid, neutral and alkaline solutions in a more convenient way, Sorensen in 1909 introduced a new scale which is known as ______ scale.
pH
It is based on the equation. $pH = -log_{10}[H^+]$ pH can thus be defined as below: pH of a solution is the logarithm of hydrogen ion concentration with a negative sign. The concentration of hydrogen ions in pure water is 0.0000001 per litre or [10^-7] pH = -log_{10}[10^-7] pH = 7 We know that water is ______. So, any solution of pH 7 will be ______.
