Front

What is the principle behind the solubility of ionic compounds in water?

Back

Ionic compounds dissolve in water due to the attraction between the ions and the polar water molecules.

Front

Define solubility.

Back

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

Front

What happens to the volume of a gas when the pressure is decreased?

Back

The volume of the gas increases.

Front

What is the relationship between pressure and volume in gases?

Back

According to Boyle's Law, pressure and volume are inversely related.
