The liquid remaining above the solid is in either case called the supernate or. When the reaction occurs in a liquid, the solid formed is called the Precipitate, or when compacted by a centrifuge, a pellet. Some 592 people had been injured in the police attack on student demonstrators, which precipitated the November revolution. In chemistry, a precipitate is an insoluble solid that emerges from a liquid solution. Precipitation is the formation of a solid in a solution or inside another solid during a chemical reaction or by diffusion in a solid.CHEMISTRY IN SOCIETY 4.3 OxidationReduction Reactions 4.3.1 The First Definition. Ironically, in view of what had happened fifty years earlier, it was now the School's success which precipitated the next crisis. precipitate would not produce as Ca a 3 (PO precipita4 ) 2.The 1929 stock market crash precipitated the collapse of the American banking system. Synonyms for PRECIPITATE: hurried, rushed, rash, precipitous, sudden, impulsive, hasty, headlong Antonyms of PRECIPITATE: deliberate, calculated, prolonged.Thus differences in 18 O/ 16 O ratio may be expected between water and calcite precipitating from it.Tetany may be triggered by hyperventilation or precipitated by vomiting or by pregnancy and lactation.What world historical events were precipitated by incidents that occurred then?.Butsy was sixteen and aware that the trip had been precipitated by a crisis.An attack on the country could precipitate a world war.For this reason, an increase in population density often precipitates a round of emigration. Precipitate chemical reaction definition Spletprecipitate: noun a substance separated from a solution or suspension by chemical or physical change usually.Many reactions of this type involve the exchange of ions between ionic compounds in aqueous solution and are sometimes referred to as double displacement, double replacement, or metathesis reactions. Both countries claimed the same area, precipitating a border war. is one in which dissolved substances react to form one (or more) solid products.► see thesaurus at cause 2 technical HC to separate a solid substance from a liquid by chemical action, or to be separated in this way → precipitate somebody into something → See Verb table Examples from the Corpus precipitate (This is why wax is insoluble in water: it is non-polar, so the wax-wax interactions are weak, but the wax-water interactions are weaker than the water-water interactions.From Longman Dictionary of Contemporary English precipitate pre‧cip‧i‧tate 1 / prɪˈsɪpɪteɪt / verb 1 formal CAUSE to make something serious happen suddenly or more quickly than was expected SYN hasten The riot was precipitated when four black men were arrested. (Ionic salts are a good example: usually they have strong interactions in the solid and solvated states.) If the interactions in the solid are weak, the compound can still be insoluble in polar solvents if the interactions with the solvent are weaker than the Coulomb interactions of the solvent molecules with other solvent molecules. Note a compound may be insoluble in one solvent yet fully miscible in another. For example, very little silver chloride dissolves in water, so it is said to be insoluble in water. In other words, any form of water which falls, whether it is in liquid or frozen form, falls as precipitation only. However, many substances are poorly soluble. Precipitation is water that falls back to the surface of the earth upon condensing in the atmosphere. It is rare for absolutely no solute to dissolve at all. For instance, if it has very strong interactions between molecules or ions in the solid state, then it won't be very soluble unless the solvation interations are also very strong. Insoluble means incapable of dissolving in a solvent. The precipitate may stay in the solution as a suspension, fall out of solution on its own, or can be separated from the liquid using centrifugation, decantation, or. Solubility depends on the relative stability of the solid and solvated states for a particular compound. A precipitation reaction is a type of chemical reaction in which two soluble salts in aqueous solution combine and one of the products is an insoluble salt called a precipitate. (It's also a little funny because many salts aren't strong electrolytes, so teachers might be telling their students to write an equation that doesn't show what's really happening.) However, it does help show what it means to be a spectator ion, since they are the same on both sides when you write it like this. No real chemist would be likely to do this because it is a nuisance.
