What is pH in Water? Definition, Importance & Level Chart

WebThe pH level of completely pure water is 7, which is exactly in the center of the scale, making it a neutral drink. However, most water includes particles that can raise the pH from 6.5 (acidic) to 8.5 (basic or alkaline). Surface water systems typically have a pH range of 6.5 to 8.5, whereas groundwater systems have a pH range of 6 to 8.5.

WebAt a pH of 7, this decreases to 0.0000001 M. At a pH of 14, there is only 0.00000000000001 M H+. pH stands for the “power of hydrogen” ³. The numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)). WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebPure water has a pH of 7 at 25°C, meaning it is neutral.
