Solutions and Solubility

Front

What happens to the solubility of KCl when the temperature decreases?

Back

The solubility of KCl decreases at lower temperatures, leading to recrystallization.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve additional solute.

Front

What effect does reducing the amount of solvent have on the rate of dissolution of a sugar cube?

Back

Reducing the amount of solvent does not increase the rate at which a sugar cube dissolves.

Front

How does shaking a bottle of cold water with mineral salts affect the dissolving rate?

Back

Shaking exposes the salts to the solvent more quickly, increasing the dissolving rate.

Front

What is one way to make a solute dissolve more quickly in a solvent?

Back

Heating the solvent can make a solute dissolve more quickly.

Front

Define solubility.

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature.

Front

What is the difference between a saturated and an unsaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve, while an unsaturated solution can still dissolve more solute.

Front

What role does temperature play in the solubility of most solids in liquids?

Back

Generally, increasing the temperature increases the solubility of most solids in liquids.

Front

What is recrystallization in the context of solutions?

Back

Recrystallization is the process where dissolved solute comes out of solution and forms solid crystals as conditions change.

Front

How does surface area affect the rate of dissolution?

Back

Increasing the surface area of a solute (e.g., by crushing it) increases the rate at which it dissolves.
