Solution
Hydronium ion :
Hydronium is H3O+ : It is formed when a hydrogen ion H+ released from an acid combines with a water moleule as :
H+ + H2O → H3O+
In hydronium ion, hydrogen ion is linked to water molecule via coordinate bond which is formed by the participation of lone pair of electrons present on oxygen atom. The structure of hydronium ion is as:
