Weak acids are those that ionize only partially in aqueous solutions,providing a much lower concentration of $H_3O^+$ ions compared to strong acids of the same molar concentration.
Strong acids: Hydrochloric acid $(HCl)$,sulphuric acid $(H_2SO_4)$,nitric acid $(HNO_3)$.
Weak acids: Citric acid,acetic acid $(CH_3COOH)$,formic acid $(HCOOH)$.
