QUE SIGNIFIE PRECIPITATE EN ANGLAIS

Précipitations (chimie)

Precipitation (chemistry)

La précipitation est la création d'un solide dans une solution ou dans un autre solide lors d'une réaction chimique ou par diffusion dans un solide. Lorsque la réaction se produit dans une solution liquide, le solide formé s'appelle le précipité. Le produit chimique qui provoque la formation du solide s'appelle le précipitant. Sans force de gravité suffisante pour réunir les particules solides, le précipité reste en suspension. Après la sédimentation, en particulier lors de l'utilisation d'une centrifugeuse pour la presser dans une masse compacte, le précipité peut être appelé une pastille. Le liquide sans précipité qui reste au-dessus du solide est appelé le surnageant ou le surnageant. Les poudres issues des précipitations ont également été historiquement connues sous le nom de fleurs. Des précipitations peuvent se produire si la concentration d'un composé dépasse sa solubilité. Les précipitations peuvent survenir rapidement à partir d'une solution sursaturée. Dans les solides, la précipitation se produit si la concentration d'un solide est supérieure à la limite de solubilité dans le solide hôte, par exemple L'extinction rapide ou l'implantation ionique, et la température est suffisamment élevée pour que la diffusion puisse conduire à une ségrégation dans les précipités.

Precipitation is the creation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid. When the reaction occurs in a liquid solution, the solid formed is called the precipitate. The chemical that causes the solid to form is called the precipitant. Without sufficient force of gravity to bring the solid particles together, the precipitate remains in suspension. After sedimentation, especially when using a centrifuge to press it into a compact mass, the precipitate may be referred to as a pellet. The precipitate-free liquid remaining above the solid is called the supernate or supernatant. Powders derived from precipitation have also historically been known as flowers. Precipitation may occur if the concentration of a compound exceeds its solubility. Precipitation may occur rapidly from a supersaturated solution. In solids, precipitation occurs if the concentration of one solid is above the solubility limit in the host solid, due to e.g. rapid quenching or ion implantation, and the temperature is high enough that diffusion can lead to segregation into precipitates.

définition de precipitate dans le dictionnaire anglais

La première définition de précipité dans le dictionnaire est de provoquer trop tôt ou plus tôt que prévu; apporter. Une autre définition de précipité est de jeter ou de tomber d'ou d'une hauteur. Le précipité doit également provoquer la condensation et la chute de la neige, de la pluie, etc., ou se condenser et tomber ainsi.
