Solutions and Solubility Curves

Front

Define solubility

Back

How much solute can dissolve in a solvent at a certain temperature.

Front

What effect does heating a solution have on solubility?

Back

Heating the solution typically allows for more solute to be dissolved.

Front

What type of solution is formed when no more solute can dissolve at a given temperature?

Back

Saturated solution.

Front

What is an unsaturated solution?

Back

A solution that can still dissolve more solute at a given temperature.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than can normally dissolve at a given temperature.

Front

What is the effect of stirring on solubility?

Back

Stirring the solute helps it dissolve faster in the solvent.

Front

What happens to solubility as temperature increases for most solids?

Back

Solubility generally increases as temperature increases.

Front

What is the solubility of KI at 10 °C?

Back

KI is the most soluble among the given options at 10 °C.

Front

What is the role of surface area in solubility?

Back

Increased surface area of the solute allows it to dissolve faster.

Front

How does particle size affect the rate of dissolution?

Back

Smaller particle size increases the rate of dissolution.
