oSorenson 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.
oThe p in p H stands for ‘potenz’ in German.
opH 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 Hless than 7 - Acidic
[H+] more than [OH-]
p Hmore than 7 - Basic
[OH-] more than [H+]
opH scale : It is a scale showing the relative strength of acids and alkalis.
oThe normal p H scale ranges from 0 to 14 as given below.
