Question

salt plus water two compounds mixed together to form a solution. the water is the solvent, the salt is the solute. students have been tasked with separating the two compounds from solution. one group set up the distillation apparatus you see here. explain the concept used to separate the salt and water. the separation of the water from the salt is based on the boiling point and condensing point of water. the separation is based on the temperature needed to change liquid water to a gas and then back again to a liquid. the boiling point. when the water evaporates from the solution, leaving salt behind. the separation of the water vapor is transferred as water vapor collects in the condensing tube. a. the separation is based on the two boiling points of the salt (higher) and the water (lower). when the solution is heated the salt (higher) and the water (lower) boiling points of the two is based on the separation. b. the separation is based on the temperature needed to change liquid water to a gas and then back again to a liquid. the boiling point. when the solution is heated the water evaporates from the solution, leaving salt behind. c. the separation is based on the two boiling points of the salt (lower) and the water (higher). when the solution is heated the salt (lower) and the water (higher) boiling points of the two is based on the separation. d. none

Explanation:

Step1: Understand distillation principle

Distillation separates components based on different boiling - points.

Step2: Analyze salt - water solution distillation

Water has a lower boiling - point than salt. When heated, water turns to vapor first (boils at 100°C under standard conditions), leaving salt behind.

Step3: Evaluate options

Option A is about boiling and condensing points in general terms which is not specific enough. Option B is incorrect as the temperature change is not the main point. Option C is correct as it correctly states that separation is based on different boiling points of salt and water with water having a lower boiling point. Option D has incorrect boiling - point relationships.

Answer:

C. The separation of the two is based on the different boiling points of the salt (higher) and the water (lower) when the solution is heated.
