pH Full Form

pH Full Form: pH stands for Potential of Hydrogen, and it is a standard to check the concentration of Hydrogen ions in the solution. In simple words, the pH is used to tell the nature of a solution whether it is acidic or basic.

pH Full Form

pH ever first introduced in 1909 by the Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory.  In 1924 it is the term pH revised as the measurement of electrochemical cells.

Vamware

Universally pH has a range from 0 to 14 where 0 represents the extremely acidic nature and 14 represents the extreme basic nature and their mid-point 7 represents the neutrality of solution. A neutral solution means it is neither acidic nor basic.

Relation Between pH and Hydrogen Ions

We use the pH scale to check the pH range of a given solution, the pH scale is inversely proportional to the concentration of Hydrogen ions present in the solution. A solution with a lower pH range has a higher concentration of Hydrogen ions and the solution with a higher pH range indicates the lower number of Hydrogen ions in the solution.

pH = -log10(aH+) = log10(aH+)

Water pH level

Temperature also plays an important role when we check the pH level of any solution, we normally check the pH level of the solution at room temperature. The pH level of water should be 7 when at room temperature (250 C)

pH indicators

pH indicators use color to represent the level of pH in a solution. In pH indicator red represent the acidic nature, blue represents the basic nature and green represent the neutrality of the solution. 

Application of pH

  • To check the pH range of soil for its fertility
  • Check the pH level of water
  • the pH level of edible things
