Which phrase best describes a redox reaction?
a
a chemical reaction involving the burning of a metal in the presence of oxygen
b
a chemical reaction resulting in the sharing of valence electrons
c
a chemical reaction resulting in a compound composed of ions held together by electrostatic forces
d
a chemical reaction involving the transfer of electrons from one reactant to another
d
a chemical reaction involving the transfer of electrons from one reactant to another
This phrase best describes a redox reaction, which stands for "reduction-oxidation" reaction. In these reactions, the oxidation states of atoms are changed due to the transfer of electrons between them. One reactant is oxidized (loses electrons) and the other is reduced (gains electrons).
