Caesium selenites

Klushina et al. [70KLU/SEL] prepared Cs2Se03 H20(cr) and reacted it with a lead nitrate solution in a calorimeter. The enthalpy data have been used in Appendix A to estimate the enthalpy change of the reaction Cs2Se03 H20(cr) + Pb — PbSe03(cr) + 2Cs + H20(I). The value obtained was - (23.00 + 1.50) kJ-moP, which furnishes the standard enthalpy of formation of caesium selenite  

Micka and Ebert [86MIC/EBE2] measured the water vapour pressure of saturated solutions in the system Cs2Se03-H2Se03-H20. From these measurements they calculated the selected Gibbs energy changes of the reactions

A less well-documented effect is that of the phase-transition temperature of certain crystals which are very sensitive to deuteration. Some crystals of ferroelectric and antiferroelectric materials, and in particular dihydrogen phosphates and hydrogen selenites, which are extensively hydrogen bonded, display this effect (Blinc and Zeks, 1974). For some crystals, such as caesium...
