pH
(Humans as organisms) scale of acidity/alkalinity. pH below 7 = acidic, pH above 7 = alkaline
pH
(= -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.
pH
A scale running from 1 to 14 and used to measure whether a soil is acid, (below pH 7) neutral (pH 7) or alkaline (above pH 7). Most garden soils are within the range of 4.5 to 8
In chemistry, pH (tʃ or tʃ) is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. The pH scale is traceable to a set of standard solutions whose pH is established by international agre...

The acidity level. The acidity is particularly important in dry-cured fermented meats, as an increase in acidity inhibits the growth of potentially harmful bacteria.

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.

(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...

[complexity] PH was first defined by Larry Stockmeyer. It is a special case of hierarchy of bounded alternating Turing machine. It is contained in P#P = PPP (by Toda`s theorem; the class of problems that are decidable by a polynomial time Turing machine with access to a #P or equivalently PP oracle), and also in PSPACE. PH has a simple logi...

Click images to enlargeScale from 0 to 14 for measuring acidity or alkalinity. A pH of 7 indicates neutrality, below 7 is acid, while above 7 is alkaline. Strong acids, such as those used in car batteries, have a pH of about 2; strong alkalis such as sodium hydroxide have a pH of about 13. Acidic fruits such as citrus...

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.

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 mathematical term for describing and identifying the concentration of hydrogen ions in a solution (such as wine). Since hydrogen ions are the most accurate definition of acidity, pH is an accurate measure of acidity in juice and wine. Winemakers who understand the relationship between pH and taste would rather know the pH of a wine than its titra...

A measure of acidity or alkalinity, pH 7 is neutral, increasing acidity is expressed as a number less than 7; increasing alkalinity as a number greater than 7. The normal pH of blood plasma is 7.35-7.45.

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.
