Hydronium ion is formed when a molecule of water combines with. a Hydrogen molecule. b Proton. c d Hydrogen you atom​

Answer 1

Explanation:

How is hydronium ion formed?

The hydronium ion always forms when an acid dissolves in water. The H+ from the acid always goes to the nearest water molecule and forms H3O+. Another way to look at the hydronium ion is to take the point of view of the proton (H+). Adding water to something is called hydration.

Answer 2

Hydronium ion is formed when a water molecule combines with a PROTON. (OPTION B)

HYDRONIUM IONS -

• The protonated water molecules of chemical formula$H_3O^+$.
• It is present in all acidic aqueous solutions.
• It is formed when a proton released from Bronsted acid combines with the water molecule in the aqueous solution.
• The molecule consists of three hydrogen atoms and one oxygen atom.
• It has trigonal pyramidal geometry and a lone pair on the oxygen atom.
• The pH of a solution depends on the concentration of hydronium in the solution.
