The question of whether polar compounds dissolve in water gets to the heart of chemical interactions, specifically the principle of "like dissolves like. For polar compounds in water, the third step is where the magic happens.
How Water's Polarity Enables Polar Compounds to Dissolve
The key is the ability to form hydrogen bonds or at least strong dipole-dipole interactions, which compensate for the energy required to separate the water molecules and the solute particles from their respective bulk phases. Water is a highly polar solvent due to its bent shape and the significant difference in electronegativity between oxygen and hydrogen atoms.
Dissolution is a three-step process: first, breaking apart the solute (endothermic), second, breaking apart the solvent (endothermic), and third, forming solute-solvent interactions (exothermic). Salt (sodium chloride) is an ionic compound, which is a subset of polar compounds, and it dissolves as water molecules surround and separate the sodium and chloride ions.
How Water's Polarity Enables Polar Compounds to Dissolve
Examples of Polar Compounds in Water The prevalence of polar compounds dissolving in water is evident in everyday life and biology. Polar compounds, which also have uneven charge distributions, can form strong interactions with water, making them generally soluble.
