The Definition of pH
pH=−log[H+]pH=−log[H+]

pH is defined as the negative logarithm of concentration of protons (H+) in a solution.

the concentration of H+ ions is 10^-6 moles/ltr.
So, when you dilute an acid so that its molarity is 10^-8, the total concentration of H+ ions in the solution is still greater than 10^-7
 which is basically the base.

Hence, you get the pH of a very dilute acid to be always less than 8.
