Answer 1

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 $(H_3O^+)$ or hydrogen ion $(H^+)$ and a base is a substance which ionizes in the water to give hydroxide ion $(OH^-)$.

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

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

Answer 2

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