Concentration factors and rate constants determined experimentally in the oyster Crassostrea gigas and the clam Mya arenaria differ widely with species and element. The physical form of the element in the water affects turnover also accumulation of radionuclides of Co, Cs, Mn, and Zn is greater in water containing suspended particles. The chemical form of the element in the water affects its accumulation. When glycine, ethylenediaminetetraacetate (EDTA), yellow stuff , or clay are added to seawater, the accumulation of Cu and Zn by the oyster differs with each test material glycine increases and EDTA decreases the accumulation of both elements. 

The most important humic substances in water are the lower-molecular-mass fulvic acids. These species tend to chelate Fe " ion, producing a yellow material called gelbstoffe (German for yellow stuff), which is responsible for much of the undesirable color found in some water. Metal ions bound with fulvic acid are hard to remove from water and, since iron is a very undesirable water impurity, drastic measures such as destruction of the fulvic acid with chlorine may be required to remove the chelated iron. Figure 3.14 illustrates a typical fulvic acid molecule. 

Related product properties are improved, for example, optical properties such as the glossiness and transparency (see Table 5.1). There are no negative consequences for dye manufacturing with the new microreactor made crystals, as the tinctorial power is the same as for conventional synthesis. Tinctorial power is a measure for the adhesion of the pigment to wool stuff or similar material. The intensification in coloration properties means that the same amount of material can be treated now with less amounts of the Yellow 12 azo pigment that reduces materials costs and increases the profitability of the pigment manufacture. 

On the street, methamphetamine is known by such names as meth, crystal meth, crystal, speed, crank or wire. Most of the stuff on the street shows the telltale signs of sloppy lab work yellow crystals, sticky crystals, or a tendency to soak up water from the air and melt. 

Note In case you have doubts about what the brown residue is in the coffee filter, you can test it Scrape the residue into a small clear glass vial or container. Add 5-10ml of methanol or acetone. The brown stuff will begin to turn white (filler) and the liquid you added will take on a tan tint. The white will stay on the bottom and will not go into solution. Your liquid will not turn yellow because there are no hormones in the residue. If you add some water to the methanol, almost all the white stuff will disappear AS are NOT SOLUBLE IN WATER. (No applause, please) Discard the test products and pat yourself on the back for getting this far. 

It was bold to suggest that mercury, a silvery metallic liquid, and sulphur, a readily fusible yellow solid, should combine to form the red mineral cinnabar, rather than the yellowish metal, gold. Indeed it seems equally bold today to advance the idea that the entire richness and diversity of the material world is formed by union of only a hundred kinds of atomic particles. Our notion that water is made from the particles of two gases, hydrogen and oxygen, in two-to-one proportion may seem no less preposterous than Aristotle s notion that water represents the impress of wetness and coldness on a matter-stuff, or than the notion of Thales of Miletus that water is itself the sole elementary source of the world.t But we have vastly more evidence to support today s fantastic contention than did the ancients. That evidence is the major content of the chemical knowledge acquired over the past three centuries. 

Picric acid is valuable as a dye-stuff, coloring silk and wool yellow as a staining medium in histological investigations and as a reagent for the alkaloids, with many of which it forms crystalline precipitates. It is also sometimes fraudulently added to beer and to other food articles, to communicate to them either a bitter taste or a yellow color. 

Allegedly, mustard received its name from its smell or taste (onion, garlic, mustard)38 or its color (which varies from yellow, to light tan, to dark brown). When mustard was first used by the Germans, the Allies called it Hun Stoffe (German stuff), abbreviated HS later, it became known as H. Mustard manufactured by the Levinstein process is also known as H it contains about 20% to 30% impurities (mostly sulfur). Distilled, or nearly pure, mus-...

Boom Bang Millions of stars of red, yellow, and green. Oh Wow On July 4th the American sky is covered with hundreds of thousands of fireworks all over the nation. It is estimated that more than 100 million dollars are spent on this spectacular display of chemicals on this day. This is perhaps one of the most ancient uses (conscious uses) of chemicals for the purpose of enjoyment. The essential ingredient is gunpowder that detonates and helps display millions of colored particles. Gunpowder is that black stuff, and used for what else but gun the same stuff. 

The U.S.P. method for stilboestrol which is more specific than the above is based on a method proposed by Goodyear, Hatfield and Marsh. 25 ml of a solution of the sample in 95 per cent ethanol, prepared to contain about 20 /jig per ml, is mixed with an equal volume of dibasic potassium phosphate solution (1 in 55) and the solution, in a quartz cell or tube, is then irradiated in ultra-violet light and its extinction measured at the maximum at about 418 m, when the maximum yellow colour has been developed. The optimum conditions (time of irradiation, distance from source of light and quality of quartz container) for maximum colour development are determined prior to making the determination, using a standard solution of stilboestrol in 95 per cent ethanol, containing 20 /ug per ml, and the stilboestrol content of the sample is determined from a comparison of the extinction of the sample solution with that of the standard solution determined at the same time under these conditions. This method has been adapted by the Analytical Methods Committee of the S.A.C. for determination of small amounts of stilboestrol (about 5 mg per pound) in complex mixtures such as animal feeding-stuffs.
