In the distillation setup shown, which component is most essential for condensing the vapor back into liquid?
A
Condenser
B
Receiving flask
C
Thermometer
D
Boiling flask
Verified step by step guidance1
Understand the purpose of each component in a distillation setup: the boiling flask is where the liquid mixture is heated to produce vapor, the thermometer measures the temperature of the vapor, the condenser cools the vapor back into liquid, and the receiving flask collects the condensed liquid.
Recall that during distillation, the vapor produced from heating must be converted back into liquid form to be collected effectively.
Identify which component is responsible for this phase change from vapor to liquid; this is the condenser, which typically uses a cooling mechanism (like water flow) to remove heat from the vapor.
Recognize that without the condenser, the vapor would not cool and condense, making it impossible to collect the purified liquid in the receiving flask.
Conclude that the condenser is the most essential component for condensing vapor back into liquid in the distillation process.
