Question

Which of the following is an oxidation reaction?
Options
A Ice melting in a soft drink
B Table salt dissolving in water for cooking vegetables
C Rusting of iron
Correct Answer
D Neutralization of HCl by NaOH
Correct Answer

Option C is the correct answer.

Detailed Explanation

Oxidation involves loss of electrons or increase in oxidation state. Rusting of iron is the oxidation of iron to form iron oxides (Fe₂O₃·xH₂O), where Fe goes from 0 to +3. The other options are physical changes or acid-base reactions, not redox.

Hint

Look for a reaction where an element combines with oxygen or loses electrons.
