Title: Transition and 12 to 14 main group metals, lanthanide, actinide and ammonium halates

Series: Solubility Data Series; editor-in-chief: Mark Salomon

Task Group
Hiroshi Miyamoto

Members: Ryo Miyamoto and Cezary Guminski

Completion Date: 2008 - project completed

This volume includes compilations and critical evaluations for the solubility of transition metal, lanthanide and actinide halates. The solubility data for the halates of metallic elements in the groups 12 to 14 are also included. Whereas the solubility of ammonium iodate was compiled and evaluated previously [1], data on ammonium chlorate (and bromate) were at that time still lacking. Data related to ammonium chlorate are available now and have therefore been 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.
