3.2 Properties of inorganic compounds
Formula (including water of crystallization), melting and boiling temperatures, density and solubility
The properties, including melting, θm, and boiling, θb, temperatures are for the substances as formulated and at
a pressure of 101.325 kPa ( ≡ 1 atm ≡ 760 Torr) and values θ /p at a pressure p. Loss of water at a specific
temperature θ /°C is denoted by –1, –2, etc., H2O/θ, and loss of oxygen, etc., similarly. Densities ρ are for 20
°C; values ρ /θ are for a temperature θ /°C. The densities of gases and vapours are not given because
approximate values can be calculated from the ideal gas laws and more accurate values can be obtained by the
use of the table in section 3.5. Solubilities S are for cold water (20 °C) and hot water (100 °C) unless some other
temperature is indicated, thus: S/θ. The solubility S is 100 times the mass of anhydrous compound soluble in a
unit mass of water. The solid in equilibrium with the saturated solution may not be the anhydrous compound
nor may it be a hydrate listed in this table. For some additional information on the solubilities of solids see the
table in section 3.6.2. For some gases the value of the absorption coefficient (A) is given: the volume of
gas measured at 0 °C and 101.325 kPa (1 atm) which will dissolve in a unit volume of water at the stated
temperature, under a partial pressure of 101.325 kPa of the gas. For some additional information on the
solubilities of gases see the table in section 3.6.1.
Abbreviations used are: a., acid; ac., acetic acid; acet., acetone; al., alcohol (ethanol); alk., alkali; anh.,
anhydrous; aq., aqueous; aq. reg., aqua regia; bz., benzene; c., cold; chl., chloroform; conc., concentrated;
d., decomposes; dil., dilute; eth., ether; exp., explodes; fus., fused; h., hot; i., insoluble; me., methanol; pyr.,
pyridine; s., soluble; sb., sublimes; si., slightly; slt., salts; tol., toluene; v., very; vac., vacuum; ∞, miscible in
all proportions.
