an insoluble or nearly insoluble solid that separates out of solution as a result of a chemical reaction
a solid compound formed during a reaction in solution
a solid produced in solution
a solid substance that forms within a liquid
A solid that is formed when a chemical that is insoluble comes out of solution. This usually happens when a chemical reaction takes place between two soluble chemicals, both in solution. One of the products is insoluble and it comes out of solution as a solid. This word can also be used as a verb, in which case, it means to come out of solution and form a precipitate.
When a dissolved substance can no longer stay dissolved and leaves the solution as a solid it is said to precipitate, to leave the solution.
A solid (used as a noun). To form a solid substance in a solution by a chemical reaction (used as a verb).
To cause (a solid substance) to be separated from a solution.—to be separated from a solution as a precipitate.
is an insoluble reaction product, which is usually crystalline and which usually grows in size to become settleable.
A percipitate is formed when a slightly soluble substance becomes insoluble and separates from a solution due to heat or a chemical reaction. The term is used to indicate the act of forming a solid and for the substance that is precipitated out of a solution.
A, solid which has come out of an aqueous solution. For example, iron from groundwater precipitates to a rust colored solid when exposed to air.
a solid formed by a reaction in solution; a precipitate settles out of solution. In the following reaction, AgCl is the precipitate: AgNO3(aq) + NaCl(aq) - AgCl(s) + NaNO3(aq).
o separate a substance out of a solution in solid form by introducing another substance.
The process that separates solids from a solution.
Mineral precipitate mineral deposited from a water solution in pores or other openings in rocks. Chemical reaction with the surrounding rock, changes in pressure or temperature, or just drying up (evaporation) can cause a mineral to precipitate out of solution. Quartz veins are common products of mineral precipitation.
as a noun, a solid substance; as a verb, to form a solid substance.
an insoluble chemical produced during a chemical reaction.
The settling out of water of dissolved sediments and chemicals.
Solids that have separated out of solution.
When solids are separated from a liquid due to a chemical or physical change.
The solid product of chemical reaction by fluids such as the zinc precipitation referred to below.
A solid which sometimes forms as a result of a chemical reaction when two solutions are mixed. The solid formed is insoluble (won't dissolve) in the solution
A substance which separates from a solution as a solid by the action of chemical reagents, temperature, pH, etc.
An insoluble product that is in the liquid mixture.
A visible solid created when two or more dissolved chemicals in the spa water combine. Precipitates give the water a cloudy or colored appearance, and they will eventually accumulate at the bottom of the spa when the water is motionless for a long period of time.
An insoluble compound which is the result of a reaction.
separates out from a liquid, a substance that was once soluble but becomes a solid due to changes in concentration or by chemical reaction
Material settled out of solution.
A substance separating, in solid particles, from a liquid as a result of a chemical or physical change. It also means to form a precipitate.
a substance, usually a solid, that separates from a fluid because of a chemical or physical change in the fluid. v: to separate in this manner
Solid particles forced out of solution by a chemical reaction. Normally settle out or give a "cloudy" look to the water.
1. the process whereby solids are left behind when liquids evaporate; for example, vast deposits of salt were created when ancient seas evaporated. 2. precipitates: the solid materials, themselves. (see: precipitation)
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
A solid that separates from a solution.
To cause a dissolved substance to form a solid particle which can be removed by settling or filtering such as in the removal of dissolved iron by oxidation, precipitation and filtration. The term is also used to refer to the solid formed and the condensation of water in the atmosphere to form rain or snow.
