What is the concentration of a solution?

Back

The concentration of a solution is the amount of solute present in a given volume of solvent, often expressed in grams per liter (g/L) or moles per liter (mol/L).

Front

What factors affect the rate at which a solute dissolves?

Back

The rate at which a solute dissolves can be affected by the temperature of the solvent, the size of the solute particles, and whether the mixture is stirred.

Front

What does it mean if a solution is saturated?

Back

A saturated solution is one in which no more solute can be dissolved at a given temperature and pressure.

Front

How can you increase the concentration of a solution?

Back

You can increase the concentration of a solution by adding more solute.

Front

Which is more concentrated: 20 g of salt in 200 ml of water or 50 g of salt in 100 ml of water?

Back

50 g of salt in 100 ml of water is more concentrated.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance, usually a liquid, that dissolves a solute to form a solution.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases as the temperature of the solvent increases.

Front

What is a dilute solution?

Back

A dilute solution is one that has a relatively low concentration of solute compared to the amount of solvent.

Front

What is a concentrated solution?

Back

A concentrated solution is one that has a relatively high concentration of solute compared to the amount of solvent.
