Solutions, Solubility Curves, Water Polarity

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. Water is the most common solvent.

Front

What is solubility?

Back

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

Front

What is a solubility curve?

Back

A solubility curve is a graph that shows the relationship between solubility and temperature for a specific solute in a solvent.

Front

How does temperature affect solubility?

Back

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

Front

What happens to bonds when water boils?

Back

When water boils, the hydrogen bonds between water molecules are broken, allowing the molecules to escape as vapor.

Front

What is the effect of stirring on solubility?

Back

Stirring increases the interaction between solute and solvent, helping the solute to dissolve faster.

Front

What is the difference between a solute and a solvent?

Back

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

Front

What is an example of a polar molecule?

Back

Water (H2O) is an example of a polar molecule due to its bent shape and the difference in electronegativity between hydrogen and oxygen.

Front

What is the significance of water's polarity?

Back

Water's polarity allows it to dissolve many ionic and polar substances, making it an excellent solvent.
