Physical Constants of Inorganic Compounds

Formula The simplest descriptive formula is given, but this does not necessarily specify the actual structure of the compound. For example, aluminum chloride is designated as AICI3, even though a more accurate representation of the structure in the solid phase (and, under some conditions, in the gas phase) is AI2CI6. A few exceptions are made, such as the use of Hg2 for the mercury(I) ion. 

CAS Registry Number Chemical Abstracts Service Registry Number. An asterisk following the CAS RN for a hydrate indicates that the number refers to the anhydrous compound. In most cases the generic CAS RN for the compound is given rather than the number for a specific crystalline form or mineral. 

Density Density values for solids and liquids are always in unit of grams per cubic centimeter and can be assumed to refer to temperatures near room temperature unless otherwise stated. Values for gases are the calculated ideal gas densities in grams per liter at 25 °C and 101.325 kPa the unit is always specified for a gas value. 

Aqueous Solubility Solubility is expressed as the number of grams of the compound (excluding any water of hydration) that will dissolve in 100 grams of water. The temperature in °C is given as a superscript. Qualitative Solubility Qualitative information on the solubility in other solvents (and in water, if quantitative data are unavailable) is given here. The abbreviations are
