Which statement is true (a) A redox reaction involves either the transfer of an electron or a change in the oxidation state of an element (b) If any of the reactants or products in a reaction contain oxygen, the reaction is a redox reaction (c) In a reaction, oxidation can occur independently of reduction (d) In a redox reaction, any increase in the oxidation state of a reactant must be accompanied by a decrease in the oxidation state of another reactant

Question: Which statement is true? (a) A redox reaction involves either the transfer of an electron or a change in the oxidation state of an element.

Which statement is true?

(a) A redox reaction involves either the transfer of an electron or a change in the oxidation state of an element.
