Solubility Unit Review

Front

What is the charge of Oxygen in H₂O?

Back

Partial negative charge.

Front

What is a supersaturated solution?

Back

A solution that contains more dissolved solute than would normally be possible under normal conditions at a given temperature and pressure.

Front

What does it mean if a molecule is soluble in water?

Back

It means the molecule can dissolve in water.

Front

True or False: Water is known as the universal solvent.

Back

True.

Front

What are solutions composed of?

Back

Solutions are composed of solutes and solvents.

Front

Define solute.

Back

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

Front

Define solvent.

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

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 the role of temperature in solubility?

Back

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

Front

What is a polar molecule?

Back

A polar molecule has a partial positive charge on one side and a partial negative charge on the other, like water (H₂O).
