The pH of an acid depends on the concentration of hydronium ions (H3O+) in the solution. The more hydronium ions present, the more acidic the solution and the lower the pH value. pH is a measure of the acidity or alkalinity of a solution on a scale from 0 to 14.
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
The pH indicates how acidic or basic a solution is.
A very acidic solution will have a very low pH.
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.

pH = -log [H+(aq)]. In words, pH is the negative logarithm (to the base 10) of the hydrogen ion concentration.
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.

The pH of a solution with a H+ concentration of 7.0 x 10^-2 M can be calculated using the formula pH = -log[H+]. In this case, pH = -log(7.0 x 10^-2) = 1.15.
Methyl yellow, which changes from yellow to red around a pH of 4.0
