By accepting an electron, the hydronium ion is converted into?
Correct answer: B. Hydrogen atoms and Water
- A. Hydrogen gas
- B. Hydrogen atoms and Water
- C. H+ ion
- D. OH- ion
Explanation
OPTION A: Hydrogen gas is not formed directly from hydronium ions. Hydrogen gas is produced through the electrolysis of water or the reaction of a metal with acid. OPTION B: Hydronium ions have three hydrogens attached. Hydronium ion homolytically breaks, allowing one of the hydrogen to escape with one electron. That leaves behind the oxygen with an unpaired electron. The electron, donated, forms a pair with the unpaired electron, stabilizing the water molecule. OPTION C: Hydronium ion is not converted into hydrogen ions by accepting an electron because it is the combination of hydrogen ions (H+) and hydroxide ions (OH-) that forms Hydronium ions (H3O+) in water.OPTION D: Hydronium ion is not directly converted into hydroxide ions through electron acceptance, as this reaction involves a transfer of a proton instead of an electron forms a pair with the unpaired electron, stabilizing the water molecule.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
