Solutions and Solubility

Front

Which would NOT increase the rate at which a sugar cube dissolves? Options: Reducing the amount of solvent, Crushing the sugar cube, Stirring the solution, Heating the solvent

Back

Reducing the amount of solvent

Front

How can you make a solute dissolve more quickly in a solvent?

Back

Heating the solvent.

Front

A solution that contains all of the solute it can hold at a given temperature is:
- diluted
- saturated
- supersaturated
- unsaturated

Back

saturated

Front

The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its

Back

solubility.

Front

Why does sample A dissolve more slowly than samples B and C?

Back

It has the smallest surface area.

Front

What happens to a KCl solution when it cools after being saturated at a higher temperature?

Back

At lower temperatures the solubility of KCl decreased and recrystallization occurred.

Front

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

Back

Shaking exposes the salts to the solvent more quickly.
