It depends on the concentration of the solution which you are going to dilute. The basic thing behind this is that actually the pH is the measure of "Activity of H+ " not only the concentration.
Now if you dilute a highly concentrated solution of acid then its pH will decrease since the more "H ions" are being made available in the solution - the reason of decrease in pH.
And the increase in pH will be observed till a certain dilution point - where all the ionizable H ions have been ionized. After that point the further dilution will result in "Decrease of concentration of (already ionized) H ions" - resulting in slight increase of the pH. and this pH may rise to the pH of the diluent (water).

The ph of an acid is pH = log 1/[H+]. Where [H+ ] is the concentration of hydrogen ions. When you dilute , the concentration of these ions decreases and the pH increases. If you have a strong acid completely dissociated if you dilute 10 times pH increases of one unit

the 1st guy is misguided.. pH measures the two acids and bases. Its is on a scale of a million-14, and concepts having a point of a million-6 in pH ability the respond is acidic, and concepts measuring 8-14 are considered to be a user-friendly answer. If the respond is at 7 which ability this is autonomous

pH=-log[H+]
Dilution increase more H+ ion, so pH will decrease.
