The chemical term for a substance that dissolves another substance is a "solvent." In a solution, the solvent is typically present in a greater amount than the solute, which is the substance being dissolved. Water is often referred to as the "universal solvent" because it can dissolve a wide variety of substances due to its polar nature and ability to form hydrogen bonds. Solvents are fundamental in chemistry and are used in various applications, such as in pharmaceuticals, cleaning products, and industrial processes. Understanding solvents is crucial for various scientific and practical uses.
