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.:

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
