Answer: C 

PH indicates the sample's acidity but is actually a measurement of the potential activity of hydrogen ions (H+) in the sample. PH measurements run on a scale from 0 to 14, with 7.0 considered neutral. Solutions with a PH below 7.0 are considered acids. Solutions with a pH above 7.0, up to 14.0 are considered ba ses. The normal range for pH in surface water systems is 6.5 to 8.5, and the pH range for groundwater systems is between 6 to 8.5. Alkalinity is a measure of the capacity of the water to resist a change in pH that would tend to make the water more acidic.

Explanation: pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs less than 7 are acidic, whereas pHs greater than 7 are alkaline (basic).
