When one compound dissolves in water, the only positive ion produced in the solution is (aq). This compound is classified as an Arrhenius acid.

Answer : The correct option is, (3) an Arrhenius acid

Explanation :

According to the Arrhenius concept, an acid is a substance which ionizes in the water to give hydronium ion [tex](H_3O^+)[/tex] or hydrogen ion [tex](H^+)[/tex] and a base is a substance which ionizes in the water to give hydroxide ion [tex](OH^-)[/tex].

When one compound dissolves in water, then only positive ion produced in the solution is [tex](H_3O^+)[/tex]. This compound is classified as an Arrhenius acid.

Hence, the correct option is, (3) an Arrhenius acid
