Mixtures and Solutions and Concentration

What are mixtures?

• two or more substances that are mixed together that can be separated from each other and the substances keep their separate properties

• a mixture in which two or more substances spread out evenly and will not settle

• the degree to which two or more substances will dissolve in another substance

• the substance in a solution that has the greatest amount

• the substance in a solution that has the least amount

What is a solution?

• mixture composed of different materials placed together but keeping their own properties

• a mixture that is defined by the particles in them.

• a way to separate solids from a liquid.

• the substance in a solution that has the greatest amount

• the substance in a solution that has the least amount

The relationship of the amount of solute to solvent determines the _____________ of the solution.

• taste

• particles

• solute

• concentration

Which process would you use to separate and analyze the solutes in a solution. During this process bands of color form on filter paper to show the different substances in the solution.

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate magnetic material from a mixture of other substances?

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate solid particles from a liquid in a mixture, with filter paper in a funnel to trap solids so that the liquids will pass through.

• Chromatography

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate solids that float from the remaining solids and other items that remain in a liquid mixture. The solids float to the top on their own or when stirred, and are then skimmed off the surface of the liquid.

• Evaporation

• Magnetic Attraction

• Filtration

• Floatation

• Sifting

Which process would you use to separate smaller solid particles from larger solid particles. A mixture of different sized solids is put into a container that has a screen material at the bottom with certain sized holes in it. The smaller particles go through the screen and the larger ones do not.
