Mixtures and Solutions

Solute

• The solid/powder in a solution (for example: Kool-Aid powder)

• The liquid in which a solute is dissolved

• A type of chemical reaction

• A mixture of two or more gases

What is an example of a solid mixture?

• A mixture of wood chips, sand, iron filings, and gravel.

• A solution of salt in water.

• A pure sample of gold.

• A gas mixture of oxygen and nitrogen.

What is a mixture?

• A mixture is a combination of two or more substances that are not chemically bonded together.

• A mixture is a single substance made up of only one type of molecule.

• A mixture is a chemical reaction between two or more elements.

• A mixture is a solution that has been filtered to remove impurities.

What happens when you mix sand and water?

• The sand dissolves completely in the water.

• You create a mixture where sand settles at the bottom and does not dissolve.

• The water evaporates and leaves the sand behind.

• The sand and water form a solid block.

Can mixtures be separated?

• Yes, mixtures can be separated into their individual components by physical means.

• No, mixtures cannot be separated.

• Mixtures can only be separated using chemical methods.

• Mixtures can be separated, but only under specific conditions.

What is a solution?

• A mixture where two substances are combined without any interaction.

• A special type of mixture where one substance (solute) is dissolved in another (solvent).

• A chemical reaction that produces a new substance.

• A solid substance that cannot dissolve in any liquid.

How are mixtures and solutions similar?

• They both involve combining two or more substances without chemical bonding.

• They both involve a chemical reaction between the substances.

• They both have a uniform composition throughout.

• They both can be separated by physical means.

How are mixtures and solutions different?

• In a mixture, substances retain their individual properties, while in a solution, the solute's properties change when dissolved.

• In a mixture, substances are chemically combined, while in a solution, they are not.

• In a mixture, the components are evenly distributed, while in a solution, they are not.

• In a mixture, the properties of the substances are enhanced, while in a solution, they are diminished.
