What is the difference between hydronium ion and hydroxonium ion ?

Please Chemistry experts help me.


They are the same thing. It is an example of co-ordinate bonding and the result of a water molecule with an added hydrogen ion (H+).

It is aqueous and looks like this: H3O+

It can be called either the hydroxonium ion, the hydronium ion or the oxonium ion.


Hydronium ion - H3O +

Hydroxide ion - OH -
