Instead, fresh diethyl ether is added to the aqueous layer, since it has the potential to extract more compound. The process is often repeated with a third extraction (not shown in Figure 4.16), with the aqueous layer from the second extraction being returned to the separatory funnel, followed by another portion of fresh organic solvent.

Over 80% of the known elements are metals and they are widely distributed in the earth’s crust either in a combined state or as free elements. The form in which a metal exists is dependent on its level of reactivity as the most reactive metals such as sodium and potassium are found as chlorides and as trioxocarbonates(IV), which are described as very stable compounds.

Apr 13, 2007 In chemistry and manufacturing, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. This can be seen in isolating copper compound from its ore. An ionic compound is dissolved with an appropriate solvent, or otherwise melted by heat, so that its ions are available in the liquid.

How Coffee Extraction Works Clive Coffee

Espresso is a much more concentrated drink: it’s made of 7-12% dissolved compounds and 88-93% water. The strength of a coffee is largely the result of the ratio of ground coffee to brew water. If too little water is used, your coffee will feel muddy and overpowering. If too much water is used, the coffee will feel thin and watery.

Liquid–liquid extraction Wikipedia

A process used to extract small amounts of organic compounds from water samples. This process is done by injecting small amounts of an appropriate extraction solvent (C 2 Cl 4) and a disperser solvent (acetone) into the aqueous solution. The resulting solution is then centrifuged to separate the organic and aqueous layers. This process is

Phytoremediation Wikipedia

Phytoremediation technologies use living plants to clean up soil, air, and water contaminated with hazardous contaminants. It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". The term is an amalgam of the Greek phyto (plant) and

How mercury is made material, history, used, processing

The Romans used mercury for a variety of purposes and gave it the name hydrargyrum, meaning liquid silver, from which the chemical symbol for mercury, Hg, is derived. Demand for mercury greatly increased in 1557 with the development of a process that used mercury to extract silver from its ore.
