39 Given the diagram of a laboratory apparatus:
This apparatus is used for which process?
(1) filtration
(2) distillation (3) chromatography
(4) electrolysis
Explanation: Filtration is a technique used to separate solid from liquid. Distillation is a technique that separates mixture components based on the process of vaporization. Chromatography separates substances based on their polarity. This apparatus is used for distillation because we see a mixture (salt water) being heated. The vapor from the water travel down the tube and condenses. It is collected in the beaker on the right.
