Solutions - Chemistry

Front

What is a solution?

Back

A homogeneous mixture composed of two or more substances, where a solute is dissolved in a solvent.

Front

Define solubility.

Back

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

Front

What is the difference between saturated and unsaturated solutions?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while an unsaturated solution can still dissolve more solute.

Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature, often achieved by heating and then cooling.

Front

What factors affect solubility?

Back

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 increases with an increase in temperature.

Front

What is the role of hydrogen bonding in water's properties?

Back

Hydrogen bonding contributes to water's high specific heat, surface tension, and solvent capabilities.

Front

What is the effect of particle size on the rate of dissolution?

Back

Smaller particles (like powdered sugar) dissolve faster than larger particles (like cubed sugar) due to increased surface area.

Front

What is a concentrated solution?

Back

A solution that contains a large amount of solute relative to the amount of solvent.

Front

What is a dilute solution?

Back

A solution that contains a small amount of solute relative to the amount of solvent.
