In a redox reaction, the substance that is oxidized:

A Gains electrons

B Loses electrons (its oxidation state increases)

C Gains protons

D Loses protons

✓ Correct Answer: Option B

Oxidation Is Loss (OIL): the oxidized species loses electrons, and its oxidation number increases.

💡 Why is B) the correct answer?

The correct answer to the question "In a redox reaction, the substance that is oxidized:" is Option B: Loses electrons (its oxidation state increases).

The other options — A) Gains electrons, C) Gains protons, D) Loses protons — are incorrect for this Everyday Science question. As explained above: Oxidation Is Loss (OIL): the oxidized species loses electrons, and its oxidation number increases.
