Solution

The process of distillation separates mixtures based on their different boiling points. In the case of a pink-colored ink solution, the mixture likely contains water and some sort of dye or pigment that gives it its color.

  1. When the solution is heated, water, which has a lower boiling point, will evaporate first. This vapor then travels up and into the condenser.

  2. Inside the condenser, the vapor is cooled down and condenses back into a liquid - this is the distillate. Since it was the water that evaporated, the distillate will be water.

  3. The dye or pigment, having a higher boiling point, will not evaporate but remain in the round-bottomed flask. So, the round-bottomed flask will contain the ink.

Therefore, the answer is B: the distillate is water and the round-bottomed flask contains ink.
