Acid radicals are the acid’s negative ion or the negative component of the acid. We get an acid radical when we remove hydrogen from an acid. Acid radicals can also be made by removing hydroxyl or mercapto groups from an acid.

A basic radical is an ion that has a basic character and originates from a base. It’s a chemical species with a positive charge. It’s also known as cation. It could be a small amount of inorganic salt. We can make a basic radical by removing the hydroxyl ion from a base.

### The difference between the acid and basic radicals are explained below

 Acid radicals Basic radicals Negatively charged radicals are called acidic radicals. Positively charged radicals are called a basic radical. Acid radicals are formed by removal of hydrogen ion (H+). Basic radicals are formed by the removal of hydroxide ion (OH–). Example: H2S04 loses one H+ ion to form HSO4– ion. Example: KOH loses OH– ion and becomes K+ ion.
