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]
Many solutes precipitate in hydrate form at low temperatures: in the previous example this is acceptable, and even useful, but it may be detrimental when, for example, the mass of water of hydration to reach a stable hydrate crystallization form is more than the available water: a single block of hydrate solute will be formed – this occurs in ...
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.
However, certain compounds can undergo precipitation in their amorphous form in vivo and can then decrease mutual bioavailability if administered together. [29] [30] Studies of GDC-0810 ASDs show a strong interrelationship between microstructure, physical properties and dissolution performance. [31]
(Reuters) - The Washington Post said on Tuesday it would lay off about 4% of its workforce or less than 100 employees in a bid to cut costs, as the storied newspaper grapples with growing losses.

The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
“Grew up off grid, and hot water from the tap meant you had to have the water pump working and you had to have water in the catchment. Plus propane for the water heater, so hot water wasn’t a ...
