Melting and Boiling Point, Density and Solubility in Water for Inorganic Compounds

Physical constants for more than 280 common inorganic compounds. Density is given for the actual state at 25°C and for liquid phase at melting point temperature.

  • Boiling point - the temperature at which a liquid turns into a gas
  • Melting point - the temperature at which a solid turns into a liquid

See Standard state and enthalpy of formation, Gibbs free energy of formation, entropy and heat capacity for thermodynamic data for the same compounds
