A substance with a pH less than 7 is considered to be acidic, while a substance with a pH greater than 7 is considered to be basic or alkaline. The lower the pH, the more acidic the substance.

WebWater temperature affects nearly every other water quality parameter. Image Credit: Fondriest pH pH, which stands for “power of hydrogen”, is a measure of how acidic or alkaline a solution is. pH is measured on a 14 point scale. A pH of 7 (pure water) is neutral; a pH higher than 7 is basic (alkaline); and less than 7 is acidic. pH is WebJan 30, 2024 · Equation 11 is correct only at room temperature since changing the temperature will change K w. The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4.
