Percent Purity

The percent of a specified compound or element in an impure sample.

Saccharic acid

A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."

Rate of Reaction

Change in the concentration of a reactant or product per unit time.

Monoprotic Acid

Acid that can form only one hydronium ion per molecule, may be strong or weak. Acid that contains one ionizable hydrogen atom per formula unit.

Flux

A substance added to react with the charge, or a product of its reduction, in metallurgy, usually added to lower a melting point.

Lewis Dot Formula (Electron Dot Formula)

Representation of the core of a molecule, ion or formula unit by showing atomic symbols and only outer shell electrons.

Valence Shell Electron Pair Repulsion Theory

Assumes that electron pairs are arranged around the central element of a molecule or polyatomic ion so that there is maximum separation (and minimum repulsion) among regions of high electron density.

 

Varieties of garnet minerals

The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in elite jewelry.

Coke

An impure form of carbon obtained by destructive distillation of coal or petroleum.

Cathode

Electrode at which reduction occurs in a cathode ray tube, the negative electrode.
