Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead(II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain through a window.
In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [1] [2] The solid formed is called the precipitate. [3] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. [4]
Forest floor interception is the part of the (net) precipitation or throughfall that is temporarily stored in the top layer of the forest floor and successively evaporated within a few hours or days during and after the rainfall event. [1]
A net ionic equation ignores the spectator ions that were part of the original equation. [1] So, the net ionic equation only shows the ions which reacted to produce a precipitate. [1] Therefore, the total ionic reaction is different from the net reaction.
In chemistry, the common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. [1] This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association / dissociation .
Mass transfer is the net movement of mass from one location (usually meaning stream, phase, fraction, or component) to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation. Mass transfer is used by different scientific disciplines for different processes ...
The net CO 2 sequestration of carbonate weathering reaction and carbonate precipitation reaction is zero. [clarification needed] Carbon-silicate cycle feedbacks. Weathering and biological carbonate precipitation are thought to be only loosely coupled on short time periods (<1000 years).
Liesegang rings - Silver-chromate precipitate pattern in a layer of gelatine Some Liesegang Rings. Liesegang rings (/ ˈ l iː z ə ɡ ɑː ŋ /) are a phenomenon seen in many, if not most, chemical systems undergoing a precipitation reaction under certain conditions of concentration and in the absence of convection.
