Answer:
HCl(g) + H₂O(l) -> Cl⁻(aq) + H₃O⁺(aq)
Explanation:
Usually when we have HCl in a lab, it's already dissolved in water. It's just HCl(aq). If we want to look at adding pure HCl, that'll be a gas. We should note that HCl is a strong acid that will break apart completely. One might not say that this is a chemical reaction so much as a dissociation. Strong acids are proton donors and form hydronium cations in aqueous solution.
