This is a measurement for liquids to determine whether they are acidic or alkaline. On a scale of one to ten, seven is considered neutral. Below seven the liquid is acidic and above seven it is alkaline. This is a factor that plays a role in the health of the lake and the fish as well as where the fish may be found in a lake.

A far from simple mathematical term for quantifying the concentration of hydrogen ions in a solution. pH is used as a measure of acidity in juice and wine. It is quite important to winemakers but its logarithmic scale makes it seem less so to the casual observer.

a measure of how acid or alkali a solution is. As the pH gets lower, the solution is more acid. At a pH of 7 the solution is neither acid nor alkali. pH is the inverse of the logarithm of the concentration of hydrogen ions.

(= -log10[H+]) A logarithmic scale for the measurement of the acidity or alkalinity of an aqueous solution. Neutrality corresponds to pH 7, whereas a 1 molar solution of a strong acid would approach pH 0, and a 1 molar solution of a strong alkali would approach pH 14.

(potential (of) hydrogen) is a logarithmic measure of the concentration of hydrogen ions (H + ) in a solution and, therefore, its acidity or alkalinity (basicity). pH = -log[H + ] The 'pH' scale extends from 0 to 14 (in aqueous solutions at room temperature). A pH value of 7 indicates a neutral (neither acidic nor basic) solution. A pH value of les...

A chemical shorthand for [p]otential of [H]ydrogen, used to express relative acidity or alkalinity in solution, in terms of strength rather than amount, on a logarithmic scale. A pH of 7 is neutral; above 7 is increasing alkalinity and below 7 is increasing acidity. Thus, a pH of 3 is 10 times more acidic than a ph of 4. See Acidity.
