Sugar water

Laboratory colonies of worker ants were fed sugar-water containing l-C14-acetate, 2-C14-acetate, or in a carefully controlled simultaneous feeding, 1-C14- or 2-C14-mevalonate. After an appropriate period, the ants were frozen and extracted with methylene chloride and the terpene aldehydes (citronellal and citral) isolated by thin-layer chromatography. These were then converted into their dini-... 

Leila is given a sealed flask of sugar water at room temperature. She places it over a Bunsen burner for a few minutes and notes condensation on the sides. Then she places the flask in an ice bath for ten minutes, and notices that ice crystals begin to form. Leila knows that the one statement that cannot be true is that —...

Ionic compounds result from the combination of a positive ion known as a cation and a negative ion called an anion. Salt is an ionic compound in which sodium cations and chloride anions chemically combined. Molecular compounds contain discrete molecular units. Molecular units or molecules are the smallest unit of a molecular compound. Atoms in a compound are held together by covalent bonds. Bonds dictate how atoms are held together in a compound or molecule, but for now, just think of ionic compounds as compounds composed of ions, and molecular compounds as compounds composed of molecules. Sugar, water, and carbon dioxide are examples of molecular compounds. 

The same amount of red-colored Kool-Aid crystals is added to a still glass of thick sugar water and a still glass of distilled water. Both are the same temperature. Neither are stirred. Which should become uniform in color first ...

Frozen desserts made from sugar, water, fruit acid, color, fruit or fruit flavoring, and stabilizer, and containing a small amount of milk solids added in the form of skim milk, whole milk, condensed milk, or ice cream mix, are known as sherbets. Federal standards for these products are included in Table 2.7. 

Fumaric acid is not permitted under UK or EU legislation for direct use in soft drinks, although it is permitted under Annex IV of Directive 95/2/EC (modified by directive 98/72/EC), with strict limits, in instant powders for fruit-, tea- or herbal-based drinks. Fumaric acid finds wide use in other countries as an acidulant, notably in the US market, where it has GRAS ( Generally Recommended As Safe ) status. Fumaric acid is currently manufactured in the United States via the acid-catalysed isomerisation of maleic acid. In terms of equivalent palate acidity it can be used at lower levels than citiic acid and typical replacement is suggested at two parts fumaric acid per three parts citric acid in water, sugar water and carbonated sugar water. 

The indispensable determinations in the analysis of diffusion juices 1 are those of the specific gravity, sugar, water and salts, the non-sugar and the quotient of purity being calculated from these in some cases the invert sugar and the acidity are calculated. 

In this, besides the specific gravity, sugar, water, non-sugar, salts and quotient of purity—determined as with diffusion juice—estimations of the alkalinity and lime are necessary. As a rule, invert sugar is not determined, as it is not present owing to the alkalinity of the juice. 

Analysis always necessitates determinations of the sugar (saccharose) and of the soluble salts, since from these is calculated the yield (rendement) on refining. Determinations may also be made of the invert sugar, water, non-sugar and, in some cases, raffinose, total ash and alkalinity sometimes sulphurous anhydride is tested for, but the colour is seldom measured. 

Another reason why there is less sugar water in the measuring cup is because when the sugar crystals dissolve in the water, the sugar molecules go into the empty spaces between the water molecules. There are spaces between molecules in a liquid.
