Solubility

Front

What is solubility?

Back

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

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 solubility of solids in liquids?

Back

Generally, the solubility of most solid solutes increases with an increase in temperature.

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 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 a supersaturated solution?

Back

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

Front

How can you make a saturated solution unsaturated?

Back

You can make a saturated solution unsaturated by adding more solvent.

Front

What is the solubility of NaNO3 at 10°C?

Back

The solubility of NaNO3 at 10°C is 80 g per 100 g of H2O.

Front

If NaNO3 has a solubility of 80 g/100 g H2O, what is its solubility in 50 g of H2O?

Back

The solubility of NaNO3 in 50 g of H2O is 40 g.

Front

What happens to the dissolving rate when temperature decreases?

Back

The dissolving rate decreases when the temperature decreases.
