    You probably don't know the pH's full form, and that's why you are here.

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

    pH Full Form

    pH ever first introduced in 1909 by the Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory . In 1924, the term pH was revised as the measurement of electrochemical cells. Universally, pH has a range from 0 to 14, where 0 represents the extremely acidic nature, and 14 represents the extremely basic nature and their mid-point, which is 7, represents the neutrality of a 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 a lower number of Hydrogen ions in the solution.

    pH = -log 10 (a H + ) = log 10 (a H + ) -

    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 at room temperature (25 0 C).

    pH Indicators

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

    Applications of pH

    • To check the pH range of soil for fertility.
    • For checking the pH level of water.
    • To check the pH level of edibles.

    pH Quick Summary

    pH Potential of Hydrogen
    Range 0 to 14
    0 to 6 Acidic
    7 Neutral
    8 to 14 Basic
    Red indicator Acidic
    Blue Indicator Basic
    Green Indicator Neutral

    Conclusion

    The pH scale is an excellent means for scientists to gauge the level of acidity or basicity of a solution. It is a usual check for many scientific experiments and applications.
