Water and Aqueous Systems

Front

What is the primary component of water's structure?

Back

Water (H₂O) is composed of two hydrogen atoms covalently bonded to one oxygen atom.

Front

What type of bond is responsible for water's unique properties?

Back

Hydrogen bonding is responsible for water's unique properties, including high boiling point and surface tension.

Front

What is the boiling point of water at standard atmospheric pressure?

Back

The boiling point of water at standard atmospheric pressure is 100°C (212°F).

Front

What is the term for the ability of a substance to dissolve in water?

Back

Solubility is the term for the ability of a substance to dissolve in water.

Front

What type of compounds typically dissolve well in water?

Back

Ionic and polar covalent compounds typically dissolve well in water.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and release large amounts of heat without significant temperature changes, stabilizing climates.

Front

What is surface tension in the context of water?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

Front

What is the effect of temperature on the solubility of gases in water?

Back

Generally, the solubility of gases in water decreases as the temperature increases.

Front

What is an example of a substance that does not dissolve in water?

Back

Hexane (C6H14) is an example of a substance that does not dissolve in water.

Front

What is the role of hydrogen bonds in water's high boiling point?

Back

Hydrogen bonds require significant energy to break, contributing to water's high boiling point.
