Question

What is the difference between hydronium ion and hydrogen ion ?

Answer 1

• Hydrogen ion is shown by the symbol H+ and hydronium ion is denoted by the symbol H3O+.

• Hydrogen ion is obtained by removing an electron from the hydrogen atom. Since this is so reactive, in aqueous medium it combines with water, to form a hydronium ion.

• Hydronium ions are also generated by protonation of water.

• Hydronium ions are stable than hydrogen ions.
