oldható

Oldható is a Hungarian adjective meaning capable of being dissolved or able to dissolve. It is most commonly used in chemistry to describe substances that can form a solution with a solvent—i.e., soluble substances. The term is formed from the noun oldat (solution) with the suffix -ható, which denotes ability or capability.

Etymology and usage notes: oldható derives from oldat (solution) and the suffix -ható, indicating that the substance can undergo the action described by the root. In everyday scientific language, oldhatóság (solubility) refers to how much of a substance can dissolve in a given solvent at a specific temperature and pressure.

In chemistry, oldhatóság depends on factors such as temperature, solvent polarity, and the presence of other ions. Solubility is commonly expressed as mass of solute per mass of solvent or per volume, such as g/100 g solvent or molarity. Substances are categorized as oldható (soluble), részben oldható or partially soluble (sparingly soluble), and nem oldható (insoluble) under given conditions. Changes in temperature can alter solubility, and some solutes are highly soluble in water while others are only sparingly soluble.

In other domains, the term oldható is less common. For mathematical or computational solvability, the standard term in Hungarian is megoldható rather than oldható.

Example: A nátrium-klorid oldható vízben. This illustrates the typical chemical usage of oldható to describe substances that dissolve in a solvent under appropriate conditions.
