A hydronium ion is formed when a positively charged hydrogen ion bonds with a molecule of water through a coordinate covalent bond.
1 HNO 3 âs conjugate base is, and waterâs conjugate acid is the hydronium ion, or. 2  Here donates the proton to water, so in the forward reaction it acts as the acid, and water is still the base. â 3 s conjugate base is NH 3, and waterâs conjugate acid is again the hydronium ion, H 3 O + .hen the forward reaction occurs, HX donates a proton to water (so it acts as the base) to form hydronium. When the reverse reaction occurs, the hydronium ion acts as the acid, donating a proton to the X - . Together, HX and X-are said to be conjugate acid-base pairs.
