11. Reactions in aqueous phase are generally faster than between a dry gas and a dry solid. 12. Foams consist of two phases, an aqueous phase and a gaseous ( air ) phase. 13. The aqueous phase consists of a mixture of non-solvents that forms a surface film. 14. Moreover, the aqueous phase that forms after the condensation of the vapor is almost pure water. 15. In aqueous phase nickel or cobalt salts can be reduced, for example, by sodium dithionite. 16. When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase . 17. The ion reacts and then forms another ion, which is then transferred back to the aqueous phase . 18. Depending on its chemical properties, a contaminant may or may not be found in the aqueous phase . 19. The inhibitor molecules essentially bind ions in aqueous phase of production fluids that could potentially precipitate as scales. 20. The method utilizes a small amount of aqueous phase formed by moistening the Li 2 MoO 4 powder.
