Balancing a redox equation by the half-reaction method is based on which of the following actions? A. the transfer of atoms B. the transfer of electrons C. the transfer of hydroxide ions D. the transfer of oxygen molecules

Respuesta :

Pretty sure it's the transfer of electrons.

Answer: Option (B) is the correct answer.

Explanation:

A chemical reaction in which there is transfer of electrons between any two species is known as a redox reaction.

For example, [tex]Cu(s) + 2Ag^{+}(aq) \rightarrow Cu^{2+} + 2Ag(s)[/tex]

Oxidation-half reaction: [tex]Cu(s) \rightarrow Cu^{2+} + 2e^{-}[/tex]

Reduction-half reaction: [tex]2Ag^{+}(aq) + 2e^{-} \rightarrow 2Ag(s)[/tex]

Thus, we can conclude that balancing a redox equation by the half-reaction method is based on action of transfer of electrons.
