Hydronium ion (H3O+) form in aqueous solution because the water molecule, H2O can accept a proton which is donated from an acid. Thus, the proton (H+) reacts with H2O to produce H3O+, the hydronium ion.

Is it possible for a solution to be both an electrolyte and an acid?

Yes!An acid (generally speaking) will form H3O+, or hydronium ions (an extra H is attached to a water molecule) in aqueous solution.An electrolyte is a solution whose aqueous solutions conduct electricity.An example would be Hydrochloric acid. Hydrochloric acid, HCl(aq) will completely disassociate in aqueous solution (dissolve), and hence form Hydronium ions.Hydronium ions are very mobile in water, and will transfer the electrical charge throughout the solution, hence making it electricity conductible.


When an acid dissolves in water it releases an ion name the ion?

The hydrogen Ion H+, however this reacts with the water to form hydronium is the aqueous cation H3O+


When a solution of an acid reacts with a solution of a base hydronium ions react with hydroxide ions to form...?

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-, 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. In other words, an acid and a base combine to neutralize each other as water.

How do acids and bases differ?

Acids are any compounds that form H+ ions in solutions while bases are a compound that produces hydroxic ions in solutions.


Why is aqueous SO2 is referred as sulphurous acid?

In water SO2 reacts to form H2SO3 which is sulfurous acid.
