Electron Deficient Compounds
Compounds that contain at least one atom (other than H) that shares fewer than eight electrons.
Effective Molality
The sum of the molalities of all solute particles in a solution.
Phosphoric Acid
H3P04, Colorless liquid or rhombic crystals, decomposes before it will boil. Used mostly in the metal etchant. Used in cleaning operations to remove encrusted surface matter and mineral scale found on metal equipment such as boilers and steam producing equipment. Also used to brighten metals and remove rust.
Radioactive Tracer
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Salicylaldehyde
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
Electron

Born-Haber Cycle
A series of reactions (and accompanying enthalpy changes) which, when summed, represents the hypothetical one-step reaction by which elements in their standard states are converted into crystals of ionic compounds (and the accompanying enthalpy changes.)
Detergent
A soap-like emulsifer that contains a sulfate, SO3 or a phosphate group instead of a carboxylate group.
