ammonia is thought to be extremely scarce in the upper troposphere because its solubility in water and reactivity with acids should lead to efficient removal in convective clouds. However, this assumption is not
Despite differences in deposit mineralogy, there is one common challenge that must be addressed, however, as it has an immediate impact on the practical and economical aspects of the REE recovery process: the individual REE sulfates display wide variations in the solubility in water with temperature...
Solubility measurements of heavy REE sulfates in water were made both on heating and on cooling so that equilibrium was approached from both precipitation and dissolution standpoints, respectively. Results are summarized in Table 1. Compositions of saturating solutions were measured by ICP-OES, which ...

Consequently, factors that raise either the solubility or the diffusivity of Pb2+ ions tend to accelerate the sulfation process. The most important of these factors are temperature and acid concentration. A temperature change from 25 to75ºC can raise the diffusivity of Pb2+ ions by orders ...
Peroxymonosulfuric (H2SO4+H2O2) oxidizes diamonds to CO2 under the correct conditions, and will probably do the job, but if that fails Peroxydisulfates are known etchants and can easily be produced electrochemically. Peroxydisulfuric acid(H2S2O8) can be prepared via anodic oxidation of H2SO4 ...

Carbon crystallization in the polarized mill annealed alloy reduced the solubility of hydrogen in this alloy and increased its mechanical strength. Hydrogen charging on the solution/mill annealed alloys at 300°C pure water increased the oxide thickness. Compared to the uncharged alloys, in the 300...
