pH refers to the potential of Hydrogen and is the measure of acidity or alkalinity of an aqueous solution. On a scale of 1 to 14, pH 7 is neutral, whilst solutions below 7 are acidic and those above 7 are alkaline or basic. Limestone and associated liming agents, all alkaline in nature, are often used for pH correction.

Used to measure acidity in cosmetic preparations.

A logarithmic scale used to measure acidity (low pH) or alkalinity (high pH).

a unit for measuring hydrogen ion concentrations. A pH of 7 indicates a "neutral" water or solution. At pH lower than 7, a solution is acidic. At pH higher than 7, a solution is alkaline.

The intensity of acidity and alkalinity, expressed as the negative logarithm of the hydrogen ion concentration. A pH of 7 is neutral; lower values indicate acidity and higher values alkalinity.

A classification of acid or base materials on a scale of 0 to 14, with 7 representing neutrality; numbers less than 7 indicate increasing acidity, and numbers greater than 7 indicate increasing alkalinity (basic conditions).

a measure of the concentration of hydrogen ions in a solution; the pH scale ranges from 0 to 14, where 7 is neutral and values less than 7 are acidic and values greater than 7 are basic or alkaline; pH is an inverted logarithmic scale so that every unit decrease in pH means a 10-fold increase in hydrogen ion concentration. Thus, a pH of 3 is 10 tim [..]

Is a measure of acidity or alkalinity. Archival paper will be neutral to alkaline (usually in the pH range 7.5 to 9.5).

An acronym for potential hydrogen which is a measure of acidity. The lower the pH, the higher the acidity.

measure of alkalinity or acidity in water and water-containing fluids. pH can be used to determine the corrosion-inhibiting characteristic in water-based fluids. Typically, pH > 8.0 is required to inhibit corrosion of iron and ferrous alloys in water-based fluids.

pH is an expression of how basic or acidic something is. pH range is from 0 to 14, where 0 is most acidic, 14 most basic, and 7 is neutral.

numeric value that describes the intensity of the acid or basic (alkaline) conditions of a solution. The pH scale is from 0 to 14, with the neutral point at 7.0. Values lower than 7 indicate the presence of acids and greater than 7.0 the presence of alkalis (bases). Technically speaking, pH is the logarithm of the reciprocal (negative log) of the h [..]

value that represents the acidity or alkalinity of an aqueous solution. It is defined as the negative logarithm of the hydrogen ion concentration of the solution[3]

The measure of acidity or alkalinity of a chemical solution, from 014. Anything neutral, for example, has a pH of 7. Acids have a pH less than 7, bases (alkaline) greater than 7.
