In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes.

The negatively charged part of the salt (anion) which has been derived from an acid is known as acidic radical. Example: Salt Magnesium chloride is obtained by action of acid HCl and base Mg(OH) 2. Thus Mg +2 ion is basic radical and Cl − is acidic radical. 2HCl+Mg(OH) 2→MgCl 2+2H 2O Acid Base Salt water Was this answer helpful? 0 0
