If you ever swam in a pool and your eyes began to sting and turn red, you felt the effects of an incorrect pH level. pH measures
Brilliant_brown [7]
Though there's no question in the statement above I would assume that you are asking about the pH of the water that is acidic. The correct statement would be:

Any liquid that has a pH less than 7 is called acidic, a pH above 7 is basic or alkaline. 

The water in the swimming pool has a high acid concentration due to the chlorine which causes the effect of redness in the eyes.
