Which of the following is strong acid?
A. Acetic acid

B. Citric acid

C. Nitric acid

D. Oxalic acid

Answer :

Nitric acid completes dissociates in aqueous solution. So it releases more H3O +. Thus it is a strong acid.

Reaction: HNO3 + H2O H3O + + NO3-


If 1M Nitric acid is taken then it will completely dissociate in aqueous solution to give 1M H3O +.


Acetic acid, oxalic acid, and citric acid do not dissociate completely


in aqueous solution, thus they are weak acids.
