Definition of Strong Acid



The acids are divided into two types i.e., strong acids and weak acids, depending upon their rate of ionization. Strong acids are such acids that have the capability to ionize completely when are present in an aqueous solution. The mechanism shows that when an acid is dissolved in water, it releases its positive and negative ions.

 


The positive ions are in the form of hydrogen ions H+. The ionization reactions are generally reversible but sometimes, the acid is dissociated into its ions so well that it makes it nearly irreversible. Then we can say that the acid is completely ionized.

 


Examples of Strong Acids:

The sulphuric acid (H2SO4) and nitric acid (HNO3) are known to be strong acids due to their good ionizing ability.
