This creates a strong dipole moment, with a partial negative charge on the oxygen and partial positive charges on the hydrogens. Examples of Polar Compounds in Water The prevalence of polar compounds dissolving in water is evident in everyday life and biology.
Why Polar Compounds Mix with Water and Form Solutions
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. 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.
Water is a highly polar solvent due to its bent shape and the significant difference in electronegativity between oxygen and hydrogen atoms. Polar compounds, which also have uneven charge distributions, can form strong interactions with water, making them generally soluble.
Why Polar Compounds Mix with Water Easily
Water is often called the universal solvent, and for good reason. Role of Polarity and Intermolecular Forces To understand why polar compounds dissolve, we must examine the forces at play.
