Expert Answer:

                   p H Scale

o   Sorenson devised a scale known as the p H scale on which the strength of acid and basic solutions could be represented by making use of hydrogen ion concentration.

o   The p in p H stands for ‘potenz’ in German.

o   pH of solution: pH of a solution is the negative logarithm to the base 10 of the hydrogen ion concentration expressed in mole per litre.

 

pH = –log10 (H+)

 

       p H = 7 - Neutral

      [H+] = [OH-]

    p H  less than 7 - Acidic

   [H+] more than [OH-]

     p H  more than 7 - Basic

      [OH-] more than [H+]

 

o   pH scale : It is a scale showing the relative strength of acids and alkalis.

o   The normal p H scale ranges from 0 to 14 as given below.
