Answer: Option (1) is the correct answer.
Explanation:
An Arrhenius acid is defined as the acid which dissociates in water to give hydrogen or \(H^{+}\) ions.
For example, \(H_{2}SO_{4} \rightarrow 2H^{+} + SO^{2-}_{4}\)
So, \(H_{2}SO_{4}\) is an Arrhenius acid as it is giving hydrogen ions upon dissociation.
Whereas a compound which dissociates in water to give hydroxide or \(OH^{-}\) ions is known as Arrhenius base.
For example, \(NaOH \rightarrow Na^{+} + OH^{-}\)
So, NaOH is an Arrhenius base as it gives hydroxide ions upon dissociation.
Thus, we can conclude that out of the given options the compound \(H_{2}SO_{4}\) is an Arrhenius acid.
