Solubility

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a saturated solution?

Back

A saturated solution is a solution that contains the maximum amount of solute that can dissolve at a specific temperature.

Front

What factors affect solubility?

Back

Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.

Front

How does temperature affect the solubility of solids in liquids?

Back

Generally, the solubility of solids in liquids increases with an increase in temperature.

Front

What is a supersaturated solution?

Back

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

Front

What is an unsaturated solution?

Back

An unsaturated solution is a solution that can still dissolve more solute at a given temperature.

Front

What is the common ion effect?

Back

The common ion effect is the decrease in solubility of a salt when a common ion is added to the solution.

Front

How does surface area affect the rate of dissolution?

Back

Increasing the surface area of a solute (e.g., granulated sugar vs. a sugar cube) increases the rate of dissolution.

What is the solubility of KNO3 at 40°C?

Back

At 40°C, the solubility of KNO3 is approximately 50 grams per 100 grams of water.

Front

What is the solubility of NaCl at 90°C?

Back

At 90°C, the solubility of NaCl is around 40 grams per 100 grams of water.
