Match the correct mixture separation technique to each description below.

Question

Column A
1. Separating a mixture of soil and water by pouring it through a funnel lined with paper. The soil gets trapped in the paper as the water passes through.:

2. A mixture of solid potassium nitrate dissolved in water is heated. Heating the mixture caused the water to evaporate, leaving the solid potassium nitrate in the container.:

3. A purple marker is separated into its individual colors as the ink moves with water up a piece of paper.

4. A mixture of methanol and water is heated. The methanol has a lower boiling point than water, so it begins to evaporate before the water. The methanol is cooled and condensed back into a liquid and is collected in a separate container.

Column B

a. Distillation

b. Chromatography

c. Evaporation

d. Filtration

choose the correct answers

Answer 1

Here are the correct matches for the descriptions provided in Column A with the techniques from Column B:

1. Separating a mixture of soil and water by pouring it through a funnel lined with paper. The soil gets trapped in the paper as the water passes through.
   Answer: d. Filtration

2. A mixture of solid potassium nitrate dissolved in water is heated. Heating the mixture caused the water to evaporate, leaving the solid potassium nitrate in the container.
   Answer: c. Evaporation

3. A purple marker is separated into its individual colors as the ink moves with water up a piece of paper.
   Answer: b. Chromatography

4. A mixture of methanol and water is heated. The methanol has a lower boiling point than water, so it begins to evaporate before the water. The methanol is cooled and condensed back into a liquid and is collected in a separate container.
   Answer: a. Distillation

So the final matches are: 1 - d, 2 - c, 3 - b, 4 - a.
