Question

Oxygen from air is separated by fractional distillation.

• A. True
• B. False

Answer 1

The correct option is A True

Fractional distillation is a separating technique used to separate the constituents of a liquid-liquid mixture having boiling point difference of less than 25${}^{\text{o}}$C.
Air around us is a homogeneous mixture of many different gases. These gases are converted to liquids to separated them individually. Oxygen is also separated by fractional distillation.
