EVAPORATING DISH Meaning and
Definition
-
An evaporating dish is a small laboratory utensil typically made of glass or porcelain, designed for the purpose of evaporating liquids. This dish is usually shallow with a wide surface area and a small spout, facilitating the process of evaporation by exposing a larger liquid surface to the surrounding air. It is commonly used in various scientific procedures, such as concentrating solutions, crystallization, and drying substances.
The dish allows for controlled evaporation of liquids by heating them on a hot plate or over a Bunsen burner. The wide surface area ensures a higher rate of evaporation, while the spout serves as a convenient outlet for pouring, transferring, or decanting the remains of the liquid after the process is completed.
Evaporating dishes are often used in chemistry experiments where it is necessary to remove the solvent from a solution without affecting the solute. They are also utilized in qualitative and quantitative analysis to isolate and concentrate substances. The choice of material, either glass or porcelain, depends on the specific requirements of the experiment or procedure, as some substances may react differently with different materials.
Overall, evaporating dishes play a fundamental role in laboratory settings, enabling scientists and researchers to perform various techniques that involve the separation, concentration, or drying of liquids and solids.

Etymology of EVAPORATING DISH
The word "evaporating" comes from the Latin word "evaporatus", which is the past participle of "evaporare". "Evaporare" is derived from the combination of the prefix "e-" meaning "out" or "away", and "vapor" meaning "steam" or "vapor".
The word "dish" has its roots in Old English, where it was originally spelled "disc". It is related to the Middle Dutch word "disch" and the German word "Tisch", all of which mean "table" or "flat surface". Over time, the meaning of "dish" has expanded to include objects used for various purposes, including containers for food or liquids.
