Solubility Data Series: Transition and 12 to 14 Main Group Metals, Lanthanide, Actinide, and Ammonium Halates

A volume of the Solubility Data Series will include compilations and critical evaluations for the solubility of transition metal, lanthanide, and actinide halates. The solubility data for the halates of metallic elements in groups 12 to 14 will also be included. Whereas the solubility of ammonium iodate has been compiled and evaluated previously, data on ammonium chlorate (and bromate) have been lacking. Data related to ammonium chlorate are now available and are included in this volume.

Compilations for the solubilities of the title halates in water and organic solvents (such as methanol, ethanol, and dimethyl sulfoxide) and those in aqueous-organic solvent mixtures, aqueous electrolytes, and buffer solutions are included in this volume. The critical evaluations and compilations of the halate solubilities deal only with the simple salts of a type of MXy (M = metal; X = halate) and do not treat complex compounds such as hexaamminecobalt(III) halates, [Co(NH3)6]X3.

The halates of these metals are related to industrial processes. For example, some halates are essential as catalysts, heat stabilizers, and blanching reagents for manufacturing polymer products such as textiles and resins. Some halates are used in pyrotechnic compounds for weather modification and colored smoke generation. The nonlinear halate crystals are important for the construction of optical devices.
