Acetone This is about the chemical compound. For the band, see Acetone (band). Acetone (systematically named propanone) is the organic compound with the formula (CH 3) 2 CO. It is a colorless, volatile, flammable liquid, and is the simplest ketone.Acetone is miscible with water and serves as an important solvent in its own right, typically for cleaning purposes in the laboratory.About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate and bisphenol A.n the laboratory, acetone is used as a polar, aprotic solvent in a variety of organic reactions, such as SN2 reactions. The use of acetone solvent is critical for the Jones oxidation. It does not form an azeotrope with water (see azeotrope (data)).

EXPERIMENT NO. 6B On the other hand, organic solvents with small dielectric constants, e.g. acetone and methanol, discourage the dispersion of protein molecules in the media. Thus, the solubility of proteins can be lowered and precipitation can be induced by lowering the effective dielectric constant of the media.n practice, it is routinely carried out at a temperature below 0ºC. Questions Calculate the volume fraction of acetone at the onset of precipitation for each protein solution. Calculate the protein yield for each case by following the same procedure as in ammonium sulfate precipitation.

Precipitation (chemistry) Chemical Precipitation. Precipitation is the creation of a solid. When the reaction occurs in a liquid solution, the solid formed is called the 'precipitate'.The chemical that causes the solid to form is called the 'precipitant'.he silver chloride (AgCl) has formed a solid, which is observed as a precipitate. This reaction can be written emphasizing the dissociated ions in a combined solution. This is known as the ionic equation.

Sodium acetate A hand warmer containing a supersaturated solution of sodium acetate which releases heat upon crystallization. Sodium acetate is also used in heating pads, hand warmers, and hot ice. Sodium acetate trihydrate crystals melt at 136.4 °F/58 °C (to 137.12 °F/58.4 °C), dissolving in their water of crystallization.

General Chemistry/Types of chemical reactions Precipitation [edit]. Wikipedia has related information at Precipitation (chemistry). A precipitation reaction occurs when an ionic substance comes out of solution and forms an insoluble (or slightly soluble) solid. The solid which comes out of solution is called a precipitate.

- Lower levels of drug loading by the addition of water to acetone may reflect the release and/or precipitation of the hydrophobic CyA from flexible and liquid like core of these transitional conformations. On the other hand, when acetone is added to water, water content in the system remains above CWC values at all times during the process (Fig. 3B).

What Are the Different Uses of Acetone? Acetone is a volatile organic compound (VOC) that is considered to have low toxicity, though improper use of it can cause serious problems. There are a number of uses for acetone, including in chemicals, solvents and nail polish remover.The most common use of acetone is to formulate other chemicals. Formulation and production of other chemicals can account for up to 75 percent of all uses of acetone.rolonged exposure to acetone may cause loss of memory. Acetone is used to make methacrylates for flat screen TVs. When acetone is used as a solvent, it means acetone's role is to dissolve some other chemical or chemicals. Nail polish remover containing acetone.

- Acetone is a colorless and highly flammable manufactured liquid. It has a distinctive fruity or mint-like odor and a pungent taste. It is also found naturally in plants, trees, volcanic gases, and forest fires, and as a by-product of the breakdown of body fat.t is found in vehicle exhaust, tobacco smoke, and landfill sites. The chemical formula for acetone is C3H6O. Acetone is used as a solvent to dissolve other substances, such as paints, varnishes, lacquers, fats, oils, waxes, resins, printing inks, plastics, and glues.

What is Precipitation? - Definition, Types & Formation However, fog and dew are not considered precipitation because these two processes are actually water condensing. As dew, it is condensing on objects. As fog, it's condensing in the air, but low to the ground. Let's look at how this works a bit more closely.

- The definition of precipitation is any form of water-liquid or solid-falling from the sky. It includes rain, sleet, snow, hail and drizzle plus a few less common occurrences such as ice pellets, diamond dust and freezing rain.ain is drops of liquid water falling from the sky. In order for the raindrops to become heavy enough to fall, droplets of water in the cloud collide together with other droplets and other particles in the air-like soot and dust-to become larger.
