Final answer:
The acidic equilibrium equation for HONH₃⁺ is HONH₃⁺(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HONH₂(aq), which indicates the partial ionization of the acid in water and the formation of a hydronium ion and the conjugate base.
Step-by-step explanation:
Acidic Equilibrium Equation for HONH₃⁺
The acidic equilibrium equation for the ion HONH₃⁺, which is the conjugate acid of hydroxylamine (HONH₂), involves the release of a proton (H⁺) and the formation of its conjugate base. Here is the balanced chemical equation representing this process, including the proper phases for all species:
HONH₃⁺(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HONH₂(aq)
This reaction shows the acid HONH₃⁺, which is in aqueous solution (aq), donating a proton to water (H₂O), which is a liquid (l). The products of this reaction are the hydronium ion H₃O⁺, also in aqueous solution, and the conjugate base HONH₂, remaining in aqueous solution as well.
Note that this reaction does not go 100% to products and establishes an equilibrium, as indicated by the double arrow (⇌).
