Solution

The video tutorial explains the concept of homogeneous mixtures, where different particles are evenly distributed. It describes solutions as solids dissolved in liquids but also highlights that solutions can involve gases or liquids in other liquids, mixtures of gases, or solids dissolved in other solids, such as metal alloys.

What is a characteristic of a homogeneous mixture?

• It is always a solid.

• It contains only one type of particle.

• The particles are unevenly distributed.

• It consists of more than one substance with evenly distributed particles.

Which of the following is a common example of a solution?

• A gas in a gas

• A solid in a solid

• A solid dissolved in a liquid

• A liquid in a gas

Can a solution involve gases?

• Yes, but only in specific conditions.

• No, solutions can only involve solids and liquids.

• Yes, solutions can involve gases.

• No, gases cannot form solutions.

What is an example of a solution involving solids?

• A metal alloy

• Air

• Oil and water

• Saltwater

Which of the following is NOT a type of solution?

• A solid in a gas

• A solid in a solid

• A liquid in a liquid

• A gas in a gas
