Solutions and Solubility Curves

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent).

Front

What is a solubility curve?

Back

A graph that shows the relationship between the solubility of a substance and temperature, indicating how much solute can dissolve in a solvent at various temperatures.

Front

Define heterogeneous mixture.

Back

A mixture where the components are not uniformly distributed and can be easily distinguished, such as salad or sand and water.

Front

What is an unsaturated solution?

Back

A solution that contains less solute than the maximum amount that can dissolve at a given temperature.

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 is the effect of temperature on the kinetic energy of particles?

Back

Increasing temperature increases the kinetic energy of particles, leading to more frequent and energetic collisions.

Front

What is a saturated solution?

Back

A solution that contains the maximum amount of solute that can dissolve at a given temperature, with no excess solute present.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature, often achieved by heating and then cooling the solution.

Front

How does pressure affect the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that dissolves the solute.
