Mixtures, Solutions & Solubility Curves

Front

What is a solute?

Back

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

Front

What is a solvent?

Back

A solvent is the substance that does the dissolving in a solution.

Front

What is a solution?

Back

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

Front

What is saturation in a solution?

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature.

Front

How does temperature affect solubility?

Back

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

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows the relationship between solubility and temperature for a specific solute.

Front

What is miscibility?

Back

Miscibility refers to the ability of two substances to mix in all proportions, forming a homogeneous solution.

Front

What is an example of a saturated solution?

Back

A saturated solution is one where no more solute can dissolve, such as saltwater when no more salt can dissolve.

Front

What happens when you stir a solute in a solvent?

Back

Stirring increases the interaction between solute and solvent particles, often speeding up the dissolving process.

Front

What is the effect of pressure on the solubility of gases?

Back

Increasing pressure increases the solubility of gases in liquids.
