Mixtures and Solutions Review

Front

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 happens to the mass of a solute when it dissolves in a solvent?

Back

The mass of the solute remains the same when it dissolves; it is still present in the solution.

Front

What is evaporation in the context of solutions?

Back

Evaporation is the process of turning a liquid into vapor, which can be used to separate a solute from a solvent.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How can density be used to classify objects?

Back

Density can be used to classify objects into those that sink or float in a fluid, such as water.

Front

What is the principle behind separating mixtures?

Back

The principle behind separating mixtures is based on the physical properties of the components, such as solubility, density, and boiling point.

Front

What is the role of a solvent in a solution?

Back

The solvent is the substance that dissolves the solute, forming a solution.

Front

What is a solute?

Back

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

Front

What is the significance of the density of an object in water?

Back

If an object's density is less than that of water (1 g/cm³), it will float; if it is greater, it will sink.
