The answer is (3) hydrogen ions as the only positive ions in solution. One ionic compound must have positive ion and negative ion at the same time. The Arrhenius base has hydroxyl ion as only negative ions in solution.

Answer: (3) hydrogen ions as the only positive ions in solution

Explanation: Arrhenius acids are substances which dissociate in water to give [tex]H^+[/tex] ions.

For example: [tex]HCl[/tex] is an Arrhenius acid.

[tex]HCl\rightarrow H^++Cl^-[/tex]

Arrhenius bases are substances which dissociate in water to give [tex]OH^-[/tex] ions.

For example: [tex]NaOH[/tex] is an Arrhenius base.

[tex]NaOH\rightarrow Na^++OH^-[/tex]
