Solutions and Solubility

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

What is solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a specific amount of solvent at a given temperature.

Front

What factors affect the rate of dissolving?

Back

The rate of dissolving is affected by temperature, surface area of the solute, and the stirring or shaking of the solution.

Front

How does temperature affect solubility?

Back

Generally, as temperature increases, the solubility of solids in liquids increases, while the solubility of gases in liquids decreases.

Front

What is the difference between a saturated and an unsaturated solution?

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 supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating the solution and then cooling it.

Front

What role does surface area play in dissolving?

Back

A larger surface area allows more solute particles to come into contact with the solvent, increasing the rate of dissolving.

Front

What is the effect of shaking a solution?

Back

Shaking a solution increases the interaction between solute and solvent, which can speed up the dissolving process.

Front

What is concentration?

Back

Concentration is the amount of solute present in a given volume of solution, often expressed in molarity (moles per liter).

Front

What is a solubility graph?

Back

A solubility graph shows how the solubility of a substance changes with temperature, indicating how much solute can dissolve in a solvent at various temperatures.
