In a macroscale simple distillation set-up, which component is responsible for condensing the vapor back into liquid?

• A. Distillation flask
• B. Receiving flask
• C. Condenser
• D. Heating mantle

Answer: (C)

Verified step by step guidance

1. Understand the purpose of each component in a simple distillation setup: the distillation flask contains the liquid mixture to be heated, the heating mantle provides the heat source, the condenser cools the vapor, and the receiving flask collects the distilled liquid.
2. Recognize that during distillation, the liquid mixture is heated in the distillation flask until it vaporizes.
3. Identify that the vapor travels through the apparatus and needs to be converted back into liquid form to be collected.
4. Know that the condenser is the component designed to cool the hot vapor, causing it to condense back into liquid.
5. Conclude that the condenser is responsible for condensing the vapor back into liquid in a simple distillation setup.
