Question

Differentiate between the following pairs based on the criteria given: 

Acetic acid and Sulphuric acid (number of replaceable hydrogen ion per molecule)

Answer 1

Acetic acid (CH3COOH)	Sulphuric acid (H2SO4)
Acetic acid has one replaceable hydrogen ion (H+) per molecule, so it is a monoprotic acid and forms only normal salts.	Sulphuric acid has two replaceable hydrogen ions (H+) per molecule, so it is a diprotic acid and forms both acid salts \[\ce{(HSO^−_4)}\] and normal salts \[\ce{(SO^2-_4)}\].
