MCQ
The removal of oxygen from a substance is called:
  • A
    Oxidation.
  • B
    Corrosion.
  • C
    Reduction.
  • D
    Rancidity.
✓

Answer

  1. Reduction.

Explanation:

Example: $\text{ZnO}\ +\ \text{C}\xrightarrow{\ \ \ \ \ \ \ \ }\text{Zn}\ +\ \text{CO}$

In this reaction, zinc loses oxygen and hence gets reduced. On the other hand, carbon gains oxygen and gets oxidised.
