What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

What is a solution?

Back

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

Front

What is the solute in a solution?

Back

The solute is the substance that is dissolved in a solvent to form a solution.

Front

What is the solvent in a solution?

Back

The solvent is the substance that dissolves the solute, typically present in a greater amount.

Front

What factors affect the solubility of a substance in water?

Back

Factors include temperature, pressure, and the nature of the solute and solvent.

Front

What is evaporation?

Back

Evaporation is the process by which liquid turns into vapor, often used to separate a solute from a solvent in a solution.

Front

How can you separate a mixture of sand and salt?

Back

You can separate sand and salt by adding water to dissolve the salt, then filtering the mixture to remove the sand.

Front

What is a saturated solution?

Back

A saturated solution is a solution that has reached the maximum concentration of solute that can be dissolved at a given temperature.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.

Front

What is concentration in the context of solutions?

Back

Concentration refers to the amount of solute present in a given volume of solvent or solution.
