BM1 Review: Aqueous Solutions and Dissolution

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In a solution, the solvent is usually present in a greater amount than the solute.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. It is present in a smaller amount compared to the solvent.

Front

What is a solution?

Back

A solution is a homogeneous mixture formed when a solute is dissolved in a solvent.

Front

What happens when you increase the surface area of a solute?

Back

Increasing the surface area of a solute increases the rate of dissolution, allowing it to dissolve faster in the solvent.

Front

What are saturated, unsaturated, and supersaturated solutions?

Back

Saturated solutions contain the maximum amount of solute that can dissolve at a given temperature. Unsaturated solutions can still dissolve more solute, while supersaturated solutions contain more solute than can typically dissolve at that temperature.

Front

What factors affect solubility?

Back

Factors that affect solubility include temperature, agitation (stirring), and the amount of solute already dissolved. The color of the solute does not affect solubility.

Front

What is the effect of temperature on solubility?

Back

Generally, increasing the temperature increases the solubility of solids in liquids, while the solubility of gases in liquids usually decreases with increasing temperature.

Front

What is agitation in the context of dissolution?

Back

Agitation refers to stirring or shaking a solution, which can increase the rate of dissolution by helping to distribute the solute particles throughout the solvent.

Front

What is a concentrated solution?

Back

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

Front

What is a dilute solution?

Back

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