Mixtures, Solutions & Solubility Curves

Front

What is a heterogeneous mixture?

Back

A mixture where the components do not mix uniformly and can be easily distinguished from one another.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout, where the individual components are not distinguishable.

Front

What is a solute?

Back

The substance that is dissolved in a solution.

Front

What is a solvent?

Back

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

Front

What is solubility?

Back

The ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature.

Front

How can you increase the rate of dissolution of a solute?

Back

By stirring the solution, increasing the temperature, or increasing the surface area of the solute.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases with an increase in temperature.

Front

What happens to the solubility of gases as temperature increases?

Back

The solubility of gases generally decreases as temperature increases.

Front

What is the effect of decreasing temperature on the rate of dissolution?

Back

Decreasing temperature generally slows down the rate of dissolution.
