what is the full form of PH?

Answer 1

pH was originally supposed to stand for French "pouvoir hydrogène," but this was translated into the English "power of hydrogen," "hydrogen power," and "potential of hydrogen." All are essentially correct.

Answer 2

PH in sense of water - It is the logarithmic reciprocal of hydrogen ion concentration in Water. In water either hydrogen ion or hydroxyl ion predominate causes water acidic or alkalic. This is measured from the number 1 to 14. The value 7 is neutral and above 7 are alkalic and below 7 is called acidic. Acidic water will auxillarate Corrosion

Answer 5

The full form of PH is Pulmonary Hypertension

Answer 6

pH - expresses the acidity or alkalinity of a solution based on the hydrogen ion concentration.

A pH of 7 is a neutral pH
A pH of above 7 is an alkaline pH
A pH of below 7 is an acidic pH

The formula for pH is:

pH = 6.1 + log ( HCO3 / DCO2)

Answer 7

An expression for the effective concentration of hydrogen ions in solution. The activity of hydrogen ions or, more correctly, hydronium ions, which are hydrated hydrogen ions H(H2O)n+, affects the equilibria and kinetics of a wide variety of chemical and biochemical reactions. Because these effects are activity-dependent, it is extremely important to distinguish between the hydrogen-ion concentration and activity. The concentration, or total acidity, is obtained by titration and corresponds to the total concentration of hydrogen ions available in a solution, that is, free, unbound hydrogen ions as well as hydrogen ions associated with weak acids. The hydrogen-ion activity refers to the effective concentration of unassociated hydrogen ions, the form that directly affects physicochemical reaction rates and equilibria. This activity is therefore of fundamental importance in many areas of science and technology.

The effective concentration of hydrogen ions in solution is expressed in terms of pH, which is the negative logarithm of the hydrogen-ion activity [Eq. (2)]. Because of the negative logarithmic (exponential) relationship, the more acidic a solution, the smaller the pH value. The pH of a solution may have little relationship to the titratable acidity of a solution that contains weak acids or buffering substances; the pH of a solution indicates only the free hydrogen-ion activity. If total acid concentration is to be determined, an acid-base titration must be performed.

Two methods, electrometric and chemical indicator (optical), are used for measuring pH. The more commonly used electrometric method is based on measurement of the difference between the pH of a test solution and that of a standard solution. The pH scale is defined by a series of reference buffer solutions that are used to calibrate the pH measurement system. The instrument measures the potential difference developed between the pH electrode and a reference electrode of constant potential. The difference in potential obtained when the electrode pair is removed from the standard solution and placed in the test solution is converted to the pH value. In the indicator method, the pH value is obtained by simple visual comparison of the color of pH-sensitive dyes to standards (for example, color charts) or by use of calibrated optical readout devices (photometers), often in combination with fiber-optic sensors..

Answer 8

the full form of PH is power of hydrogen, in french it is also called piuncai of hydrogene it is used to identify the acidic or basic character of any substance

Answer 9

power of hydrogen. On ph scale it is 0-14. As 7 is nuetral and below is acidity and above it is alkaline.

Answer 10

The pH scale is a reverse logarithmic representation of relative hydrogen proton (H+) concentration
