Telephone. Finally, of course, you can suggest other common or your own abbreviations and use them (consistently! (Phenyl is pronounced with the accent on phen-, whereas phenol is pronounced with the accent on -ol.) The scale is logarithmic in nature, meaning that every whole pH value represents a change of 10 times the previous value. The term "pH" is used within chemical formulas to indicate the presence of hydrogen. The pH scale is a scale that is used to rank the relative basicity or acidity of substances to other substances, based on the amount of hydrogen ion activity in a substance. PH. ). Illustrated Glossary of Organic Chemistry. pH value varies in the range of 1 to 14. pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. pH is a measure of the hydrogen ion activity, typically in aqueous solution. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion into numbers between 0 and 14. Potential of Hydrogen - negative 10-base log (power) of the positive hydrogen ion concentration; measure of acidity. Definitions of pH, pOH, and the pH scale. Phenyl (phenyl group; Ph): A portion of molecular structure equivalent to benzene minus one hydrogen atom: -C 6 H 5.Sometimes abbreviated as Ph. Not to be confused with phenol, fennel, or funnel, or pH. PH. Definition. The pH value of pure water is 7. pH may be seen as an abbreviation of the power of hydrogen-or, more fully, the concentration of hydrogen ion in a liquid. It was an easy way to represent the concentration of hydrogen ions in a solution during titrations. Public House. PH: Plataforma Humanista: PH: Physical Header: PH: Primal Heuristic (algorithm) PH: Porphyric Hemophilia (disease) PH: Phalasteen.com (website) pH: Puissance de Hydrogen (French: power of hydrogen) PH: Protection and Handset: pH: Potential of Hydrogen - negative 10-base log (power) of the positive hydrogen ion concentration; measure of acidity: PH: Poké Hunters (webcomic) PH This unit was introduced by biochemist Søren Peter Lauritz Sørensen in 1909. pH is a logarithmic measure of the concentration of hydrogen ions or protons (H+), in a solution. Mathematical definition of pH is a little less intuitive but more useful in general. pH stands for potential hydrogen with the “p” meaning potential and the “H” standing for hydrogen. Learn more about pH. Philippines (Internet top level domain) PH. pH Abbreviation. pH (Abbreviation) The negative of the logarithm to the base 10 of the concentration of hydrogen ions, measured in moles per liter; a measure of acidity or alkalinity of a substance, which takes numerical values from 0 (maximum acidity) through 7 (neutral) to 14 (maximum alkalinity). PH. In pH, the p stands for -log 10 and the H stands for hydrogen ion activity: pH = -log 10 a H + The term “pH” is an abbreviation for the “potential of hydrogen.” pH is a unit of measurement which represents the concentration of hydrogen ions in a solution. P h A c [1] Where the symbols would need to be defined to mean ethyl, phenyl, acetyl, methyl and tert -butyl, respectively. The relationship between acid strength and the pH of a solution. Calculating the pH of a strong acid or base solution. What does pH mean? It states that the pH equals the negative logarithmic value of the concentration of hydrogen ion (H+) pH = -log [H+]
