Answer:
A pure solutions has these ions: H⁺ and Cl⁻
An aqueous solution has these ions, H₃O⁺, Cl⁻ and OH⁻ from water
Explanation:
Pure hydrochloric acid can be dissociated as this:
HCl → H⁺ + Cl⁻
If you mix HCl and water, this procces gives protons to the medium
HCl + H₂O → H₃O⁺ + Cl⁻
2H₂O → H₃O⁺ + OH⁻
