Redox Reactions

Redox reactions are considered to be the chemical reactions involving both oxidation and reduction processes. They are actually oxidation-reduction reactions. The term redox is made from two words where “red” comes from reduction and “ox” comes from oxidation. During a redox reaction electron transfer takes place in such a way that one chemical compound gets reduced and the other one gets oxidized.

Question

1. Which is statement is INCORRECT?
a. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of
a molecule, atom, or ion changes by gaining or losing an electron.
b. Reduction is a process in which an atom gains an electron and therefore decreases (or
reduces its oxidation number).
c. Oxidation is a process in which an atom gains an electron and therefore increases its
oxidation number.
d. An electron-donating species which tends to hand over electrons can be referred to as a
reducing agent.
2. What chemical process must always accompany a reduction process?
a. oxidation
c. reduction
b. balancing reaction
d. half-reaction
