Separating Mixtures

Which of the following in NOT an example of an insoluble mixture?

• rice and water

• salt and water

• sand and water

• iron and sand

Which of the following is NOT an example of a soluble mixture

• salt and water

• sugar and water

• sand and water

• milo and milk

If something is insoluble, it...

• is poorly dissolvable

• does dissolve

• can freeze time

• is mean

Solubility is the ability of a solid, liquid, or gaseous chemical substance to dissolve and form a solution

• True

• False

Which separation technique uses gravity to separate heavier substances from a suspension

• Gravity separation eg. catching a fish in a net

• Gravity separation eg. panning for gold

• Filtration eg. filtering dirt from water

• Magic separation eg. pulling a rabbit from a hat

What separation technique allows small particles to get through but traps larger particles

• sieving

• magnetic separation

• diffusion

• decantation

What technique uses a filter – different filters can be used for solids from gases, solids from liquids, liquids from gases, liquids from other liquids

• Chromosomes

• Fluctuation

• Filtration

• Frustration

What separation technique is best for removing magnetically susceptible material from a mixture?

• Recycling

• Filtration

• Magic separation

• Magnetic separation

What is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below.

• gentle pour

• Decantation

• Sinkable separation

• Flowpour separation

This separation technique results in the formation of pure solid particles of a substance from a solution containing the dissolved substance

• Crystalization

• Decantation

• Filtration

• Separation
