name: teacher: date: chemistry: u1l5 mixture separation prepwork part 1: mixture separation practice q1 ***match the following mixtures by the best separation technique to use: you can match a mixture to more than one separation technique if it applies. 1. a muddy puddle 2. a mixture of vinegar and water 3. a mixture of oil and water 4. a bowl of cereal and milk 5. a mixture of black ink and water 6. sugar dissolved in water a. filtration b. chromatography c. decanting d. distillation e. evaporation q2 ... and distillation. when would each be used?

Explanation:

To solve this mixture - separation matching problem, we analyze each mixture and the appropriate separation technique:

1. A muddy puddle

A muddy puddle consists of solid mud particles suspended in water. Filtration is a technique that uses a filter medium (like filter paper) to separate solid particles from a liquid. The liquid (water) can pass through the filter, while the solid mud particles are retained. So, for a muddy puddle, the separation technique is Filtration (A).

2. A mixture of vinegar and water

Vinegar (acetic acid in water) and water form a homogeneous mixture, but they have different boiling points. Distillation is used to separate components of a homogeneous mixture based on differences in their boiling points. When the mixture is heated, the component with the lower boiling point (or more volatile component) vaporizes first, and then the vapor is condensed to get the pure component. So, for a mixture of vinegar and water, the separation technique is Distillation (D).

3. A mixture of oil and water

Oil and water are immiscible liquids, and they form separate layers (oil is less dense and floats on water). Decanting is the process of carefully pouring off the top layer (oil) from the bottom layer (water) without disturbing the sediment (or in this case, the lower - density liquid layer). So, for a mixture of oil and water, the separation technique is Decanting (C).

4. A bowl of cereal and milk

Cereal is a solid, and milk is a liquid. Filtration can be used here as the solid cereal particles can be retained by a filter, and the liquid milk can pass through. So, for a bowl of cereal and milk, the separation technique is Filtration (A).

5. A mixture of black ink and water

Black ink is a mixture of different colored dyes dissolved in water. Chromatography is a technique used to separate components of a mixture (especially in a solution) based on their different affinities for a stationary phase and a mobile phase. In paper chromatography (a common type), the ink mixture is spotted on paper, and as the solvent (mobile phase) moves up the paper, the different dyes (components of ink) move at different rates based on their solubility in the solvent and their attraction to the paper (stationary phase). So, for a mixture of black ink and water, the separation technique is Chromatography (B).

6. Sugar dissolved in water

Sugar dissolved in water forms a homogeneous mixture. Evaporation is a technique where the liquid (water) is evaporated (converted to vapor) by heating, leaving behind the solid solute (sugar). So, for sugar dissolved in water, the separation technique is Evaporation (E).

Final Matches:

1. A muddy puddle - A (Filtration)
2. A mixture of vinegar and water - D (Distillation)
3. A mixture of oil and water - C (Decanting)
4. A bowl of cereal and milk - A (Filtration)
5. A mixture of black ink and water - B (Chromatography)
6. Sugar dissolved in water - E (Evaporation)

Distillation is used to separate components of a homogeneous mixture based on differences in their boiling points. When the mixture is heated, the component with the lower boiling point (or more volatile component) vaporizes first, and then the vapor is condensed to get the pure component. So, for a mixture of vinegar and water, the separation technique is Distillation (D).

Decanting is the process of carefully pouring off the top layer (oil) from the bottom layer (water) without disturbing the sediment (or in this case, the lower - density liquid layer). So, for a mixture of oil and water, the separation technique is Decanting (C).

4. A bowl of cereal and milk

Cereal is a solid, and milk is a liquid. Filtration can be used here as the solid cereal particles can be retained by a filter, and the liquid milk can pass through. So, for a bowl of cereal and milk, the separation technique is Filtration (A).

5. A mixture of black ink and water

Black ink is a mixture of different colored dyes dissolved in water. Chromatography is a technique used to separate components of a mixture (especially in a solution) based on their different affinities for a stationary phase and a mobile phase.

6. Sugar dissolved in water

Sugar dissolved in water forms a homogeneous mixture. Evaporation is a technique where the liquid (water) is evaporated (converted to vapor) by heating, leaving behind the solid solute (sugar). So, for sugar dissolved in water, the separation technique is Evaporation (E).
