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 .
Deflocculation is the opposite of flocculation, sometimes known as peptization. Sodium silicate (Na 2 SiO 3 ) is a typical example. Usually, in higher pH ranges, in addition to low ionic strength of solutions and domination of monovalent metal cations , the colloidal particles can be dispersed. [ 21 ]
Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.
Precipitate or precipitates, or variant, may refer to: Precipitate, the product of chemical precipitation; Precipitate, the product of meteorological precipitation; Precipitate, an EP released by Interpol (rock band) "Precipitate", a song by Interpol from the EP Fukd ID 3; Precipitate, a 2003 episode of The Dead Zone
Precipitation. Precipitation is the formation of a solid in a solution or inside another solid during a chemical reaction. It usually takes place when the concentration of dissolved ions exceeds the solubility limit [34] and forms an insoluble salt. This process can be assisted by adding a precipitating agent or by the removal of the solvent.
The term precipitation is normally reserved for describing a phase change from a colloid dispersion to a solid (precipitate) when it is subjected to a perturbation. [19] Aggregation causes sedimentation or creaming, therefore the colloid is unstable: if either of these processes occur the colloid will no longer be a suspension.
Complementary antonyms are word pairs whose meanings are opposite but whose meanings do not lie on a continuous spectrum (push, pull). Relational antonyms are word pairs where opposite makes sense only in the context of the relationship between the two meanings (teacher, pupil). These more restricted meanings may not apply in all scholarly ...
