Mixtures and Solutions

Front

What is a mixture?

Back

A mixture is a combination of two or more substances where each substance retains its own properties.

Front

What is a solution?

Back

A solution is a type of mixture where one substance (the solute) is completely dissolved in another (the solvent), resulting in a homogeneous mixture.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the different components can be seen and are not uniformly distributed.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, and the individual components are not visible.

Front

What is a colloid?

Back

A colloid is a mixture where very small particles of one substance are evenly distributed throughout another substance, but they do not settle out.

Front

How can you determine the concentration of a solution?

Back

You can determine the concentration of a solution by comparing the amount of solute to the amount of solvent.

Front

What does it mean for a solution to be concentrated?

Back

A concentrated solution has a large amount of solute compared to the amount of solvent.

Front

What does it mean for a solution to be diluted?

Back

A diluted solution has a small amount of solute compared to the amount of solvent.

Front

How do you compare the density of solutions?

Back

You compare the density of solutions by measuring the mass of a certain volume of each solution.

Front

What is the effect of temperature on solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases, while the solubility of gases decreases.
