A concentrate is a form of substance which has had the majority of its base component (in the case of a liquid: the solvent) removed. Typically this will be the removal of water from a solution or suspension such as the removal of water from fruit juice. One benefit of producing a concentrate is that of a reduction in weight and volume for transportation as the concentrate can be re-constituted at the time of usage by the addition of the solvent. Look up substance in Wiktionary, the free dictionary. ... For other uses, see Solvent (disambiguation). ... Water is a chemical substance that is essential to all known forms of life. ... Dissolving table salt in water This article is about a chemical solution; for other uses of the term solution, see solution (disambiguation). ... Flour suspended in water In chemistry, a suspension is a colloidal dispersion (mixture) in which a finely-divided species is combined with another species, with the former being so finely divided and mixed that it doesnt rapidly settle out. ... Juice is the liquid naturally contained in plants. ...
Concentrated juice was developed during World War II to provide nourishment for the armed forces.
Concentrate can also be the residue valuable metal from which most of the waste rock has been removed. The residue metal becomes the raw material for smelting. Electric phosphate smelting furnace in a TVA chemical plant (1942) Chemical reduction, or smelting, is a form of extractive metallurgy. ...
My mind used to be so restless that I couldn't concentrate for more than a few minutes at a time before I got distracted.
By now I had not only found where concentration was located in the brain, I discovered that exercising your executive function and attentional control center directly is the most natural and quickest way to improve focus and concentration.
Concentrate at will and examine in depth any given topic, even in extremely distracting situations for extended periods of time and with less effort.
Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" or "weak" for solutions of relatively low concentration and of others like "concentrated" or "strong" for solutions of relatively high concentration.
The difference between formal and molarconcentrations is that the formal concentration indicates moles of the original chemical formula in solution, without regard for the species that actually exist in solution.
This works fine for gasconcentrations (e.g., ppmv of carbon dioxide in the ambient air) but, for concentrations of non-gaseous substances such as aerosols, cloud droplets, and particulate matter in the ambient air, the concentrations are commonly expressed as μg/m³ or mg/m³ (e.g., μg or mg of particulates per cubic metre of ambient air).
