Question

Which of the following statements is false about redox reactions?

a. Reduction is the gain of electrons.
b. Oxidation occurs at the anode of an electrochemical cell.
c. Oxidation is the loss of electrons.
d. Oxidation and reduction cannot both occur in the same chemical reaction.
e. Oxidation-reduction reactions involve the transfer of electrons.

Answer 1

`\huge\boxed{\sf Option\ D.}`

Step-by-step explanation:

Redox reaction:

• When oxidation and reduction occur simultaneously in a chemical reaction, reaction is called a redox reaction.

Oxidation involves:

• gain of oxygen.
• loss of hydrogen.
• loss of electrons.
• increase in oxidation state.
• occurring at anode.

Reduction involves:

• loss of oxygen.
• gain of hydrogen.
• gain of electrons.
• decrease in oxidation state.
• occurring at cathode.
