Understand the concept of solubility: Solubility is the ability of a substance to dissolve in a solvent, forming a homogeneous solution. Water is a polar solvent, meaning it has a partial positive charge on one side and a partial negative charge on the other.

Identify the types of substances: Ionic compounds consist of positive and negative ions, which can interact with the polar water molecules. Polar molecules have an uneven distribution of charge, allowing them to interact with water's polar nature.

Consider the interaction between water and ionic compounds: The positive and negative ions in ionic compounds are attracted to the opposite charges in water molecules, facilitating the dissolution process.

Consider the interaction between water and polar molecules: Polar molecules can form hydrogen bonds or dipole-dipole interactions with water, enhancing their solubility.

Recognize the exceptions: Nonpolar molecules and noble gases do not interact well with water due to their lack of charge or polarity, making them generally insoluble in water.
