Solubility and Solutions

Front

What is Solubility?

Back

A measure of how much solute can dissolve in a solvent.

Front

What type of solvent is required to dissolve nonpolar substances like oil?

Back

Nonpolar solvent.

Front

How many grams of sugar can dissolve in 100 mL of water at 20°C according to the solubility curve?

Back

200 g.

Front

What is a supersaturated solution?

Back

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

Front

What factors affect the rate of solubility?

Back

Temperature, surface area, and agitation.

Front

Why does a smaller surface area of a solute lead to slower dissolution?

Back

It has fewer particles exposed to the solvent.

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 happens to the solubility of most solids as temperature increases?

Back

It generally increases.
