löslicher

löslicher is a German adjective meaning "able to be dissolved" or "soluble." It describes substances that can dissolve in a solvent at a given temperature. The noun form is Löslichkeit (solubility). In everyday and scientific language, one speaks of lösliche Stoffe (soluble substances) and unlösliche Stoffe (insoluble substances). The comparative form is used to compare solubilities, as in "Salz ist löslicher als Zucker in Wasser." The superlative is "am löslichsten."

In chemistry and related fields, solubility describes how much of a substance can dissolve in a solvent before the solution becomes saturated. It influences drug formulation, nutrient availability, and environmental mobility. A soluble compound has higher bioavailability or mobility than an insoluble one.

Solubility depends on temperature, pressure (for gases), and the nature of solvent and solute. It is commonly expressed as grams of solute per 100 grams of solvent (solubility), or as molarity, molality, or mole fraction. The solubility product constant (Ksp) characterizes equilibrium for sparingly soluble salts.

Common soluble substances include table salt (NaCl) and sugar in water; gases like CO2 are soluble under certain conditions. Substances may be soluble in one solvent but insoluble in another; solubility is thus solvent-specific.

Etymology: the term derives from lösen (to dissolve) plus the suffix -lich; the concept is widespread in German-language science and education.
