Mixtures and Solutions

What is a mixture?

• A substance made of two or more chemically combined atoms

• A substance made of two or more substances that are together in the same place but not chemically combined

• A homogeneous mixture that looks the same throughout

• A heterogeneous mixture that has distinct components

Which type of mixture has distinct components that can easily be seen and sorted?

• Colloid

• Suspension

• Homogeneous Mixture

• Heterogeneous Mixture

What is a colloid?

• A homogeneous mixture that looks the same throughout

• A heterogeneous mixture containing small, undissolved particles that do not separate or settle out if the mixture is undisturbed

• A mixture with particles that can be seen and easily separated by settling or filtration

• A homogeneous mixture of a solvent and one or more solutes

What is a suspension?

What is a solvent?

• The part of the solution that is usually present in the largest amount

• The substance that is dissolved by the solvent

• A measure of how much solute will dissolve in a solvent

• A solution that can no longer dissolve a solute

What is solubility?

• A measure of how much solute will dissolve in a solvent

• The part of the solution that is usually present in the largest amount

What is the difference between a physical change and a chemical change?

• A physical change is a change in which the substance's identity remains the same, while a chemical change is a change in which new substances are formed.

• A physical change is a change in which new substances are formed, while a chemical change is a change in which the substance's identity remains the same.

• A physical change is a change in which the substance's identity remains the same, while a chemical change is a change in which the physical properties of the substance change.

• A physical change is a change in which the physical properties of the substance change, while a chemical change is a change in which new substances are formed.
