What is an unsaturated solution?

Back

An unsaturated solution is one that contains less than the maximum amount of solute that can be dissolved in a solvent.

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 an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Examples include hydrogen, oxygen, and carbon.

Front

What is a saturated solution?

Back

A saturated solution is one in which the maximum amount of solute has been dissolved in the solvent, and any additional solute will remain undissolved.

Front

What is a supersaturated solution?

Back

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature, often achieved by heating the solution.

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.
