Solubility

Front

What is solubility?

Back

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

Front

Which solute does not increase in solubility as temperature rises?

Back

Ammonia (NH3) is a solute that does not increase in solubility with rising temperature.

Front

What factors affect the rate of solubility?

Back

Factors include temperature, surface area of the solute, and agitation (stirring).

Front

What is a solution?

Back

A solution is a homogeneous mixture made up of solutes and solvents.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between a slightly positive hydrogen atom in a polar molecule and a negatively charged atom.

Front

How does surface area affect solubility?

Back

A larger surface area allows more solute particles to interact with the solvent, increasing the rate of dissolution.

Front

What is the role of temperature in solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids but decreases the solubility of gases.

Front

Define solute and solvent.

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

Front

What is the difference between a homogeneous and heterogeneous mixture?

Back

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.
