Step 1
Which separation technique in the laboratory requires a condenser?
Answer
The correct answer is D. Distillation.
In distillation, a mixture is heated to evaporate the solvent, which then rises and passes through a condenser. The condenser cools the vapor, turning it back into liquid, allowing for the separation of components based on their boiling points. This technique is crucial for separating liquid mixtures, especially when accurate separation is needed.
