Question

Choose all of the statements from below which are true about oxidation and reduction.

A. Oxidation and reduction are opposite processes with respect to bookkeeping electrons.


B. Oxidation is what happens when an element in a substance gains electrons.


C. Electrons appear on the right side of an oxidation half reaction.


D. An oxidant is an oxidizing agent, which becomes oxidized during the course of a redox reaction.


E. Reduction is what happens when an element in a substance decreases its oxidation number.


F. Electrons appear on the right side of a reduction half reaction.


A reductant is a reducing agent, which becomes reduced during the course of a redox reaction.

Answer 1

A. Oxidation and reduction are opposite processes with respect to bookkeeping electrons.TRUE, one happens as the other happens

B. Oxidation is what happens when an element in a substance gains electrons. FALSE, they lose electrons

C. Electrons appear on the right side of an oxidation half reaction. TRUE, because they are being lost, or stirpped in the final stage

D. An oxidant is an oxidizing agent, which becomes oxidized during the course of a redox reaction. FALSE, oxidizing agents are reduced

E. Reduction is what happens when an element in a substance decreases its oxidation number. TRUE, since decrease in oxidation number means, that it is more negatively charge, that is, it gained electrons

F. Electrons appear on the right side of a reduction half reaction. FALSE, electrons are gained in the reactants, therefore must be in th eleft side
