Mixtures and Solutions Investigation 1

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution. For example, salt is a solute when it is dissolved in water.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute. Water is a common solvent.

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically combined. Examples include sand and salt.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent). For example, saltwater.

Front

What happens to a solute when it dissolves in a solvent?

Back

When a solute dissolves in a solvent, it breaks down into smaller particles and spreads evenly throughout the solvent.

Front

What is the mass of 1 liter of water?

Back

1 liter of water has a mass of approximately 1000 grams.

Front

How can you separate a mixture of sand and salt?

Back

You can separate sand and salt by dissolving the salt in water, filtering the mixture, and then evaporating the water to get the salt back.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into vapor, often used to separate a solute from a solvent.

Front

What is the role of a filter in separating mixtures?

Back

A filter is used to separate solid particles from liquids or gases by allowing the liquid or gas to pass through while trapping the solids.

If you dissolve 20 g of sugar in 80 g of water, what is the mass of the solution?

Back

The mass of the solution is 100 g (20 g of sugar + 80 g of water).
