olga_2 [115]

Answer:

H₃O⁺ and Cl⁻

Hydrochloric acid, a strong acid will ionize completely in solutions.

When acids ionize in water, they produce excess hydroxonium ions in such solution.

The HCl and H₃O⁺  forms a conjugate pair and likewise the H₂O and Cl⁻

In this ionization, water acts as the base.
