Solutions at Work: What Are Solutions?

The video explains that solutions are mixtures of two or more substances evenly distributed. It covers the properties of solutions, the process of dissolving, and the roles of solute and solvent. Examples include saltwater, juice, and air. Not all substances are soluble in water, like oil. Solutions can be gases, like air, or solids, like alloys. The video highlights that solutions have uniform properties throughout.

What is a solution?

• A mixture of gases only

• A single substance with no mixture

• A type of mixture made of two or more substances that are evenly distributed

• A mixture of substances that are not evenly distributed

Which of the following is an example of a solute?

• Air

• Oil

• Powdered fruit drink

• Water

Why is oil not considered a solution when mixed with water?

• Because oil is soluble in water

• Because oil evaporates in water

• Because oil is insoluble and does not dissolve in water

• Because oil forms a uniform mixture with water

Which of the following is a gaseous solution?

• Saltwater

• Juice

• Brass

• Air

What is an alloy?

• A liquid solution of metals

• A solid solution of metals or non-metals dissolved in metals

• A mixture of gases and liquids

• A gaseous solution of metals
