Hydronium ion, H3O+, is what gives a low pH to an aqueous solution. Hydronium ion is made when an acid donates a hydrogen ion to a water molecule.    Hydroxide ion, OH- â¦ , gives a higher pH to an aqueous solution. Hydroxide ions are found in bases; a base donates hydroxide ions to water.   Combining H3O+ + OH-makes 2 H2O.he hydronium ion is a polyatomic ion that forms when an acid releases a proton (H+) to a water molecule.
