The solubility of elemental mercury (Hg') at temperatures between 30 and 210°C was determined by direct sampling of mercury saturated water contained in a fixed volume stainless steel autoclave. The temperature dependence of the solubility was best represented by the equation log,^^, = -11.879 + 0.01206T where xHg is the mole fraction of dissolved Hgo and T is the temperature in degrees Kelvin....

The ability of a particle to serve as a cloud condensation nucleus in the atmosphere is determined by its size, hygroscopicity and its solubility in water. Usually size and hygroscopicity alone are sufficient to predict CCN activity. Single parameter representations for hygroscopicity have been shown to successfully model complex, multicomponent particles types. Under the assumption of either c...

Influence of polishing methods on water sorption and solubility of denture base acrylic resins was studied. Eighty samples were divided into groups: Classico (CL), and QC 20 (QC) - hot water bath cured; Acron MC (AC), and Onda Cryl (ON) - microwave cured; and submitted to mechanical polishing (MP) - pumice slurry, chalk powder, soft brush and felt cone in a bench vise; or chemical polishing (CP...

PURPOSE A predictive method was proposed to predict solubility of drugs in water-ethanol mixtures at various temperatures based on the Jouyban-Acree model. The model requires the experimental solubility data of the drug in mono-solvent systems. METHODS The accuracy of the proposed prediction method was evaluated using collected experimental solubility data from the literature. The proposed me...

The solubility of uric acid in water was determined by His and Paul 1 to be about I in 39,500. Uric acid is very slightly dissociated, less than IO per cent. in saturated solution. His and Paul have, however, confined the solubility within too narrow limits. If one shakes large crystals of uric acid in water for a day at room temperature, one cannot reach a solubility of I in 40,000; if, howeve...

Background and objectives: Essential oils (volatiles) are aromatic oily liquids prepared from different parts of plants and demonstrate various therapeutic and cosmetic properties. The dissolution of essential oils are not desirable in water, therefore the aim of this research was evaluation and selection the best co-solvents for increasing their solubility and bio availability...

Olmesartan medoxomil is a poor water soluble drug. There are numerous approaches available and reported in literature to enhance the solubility of poor water soluble drugs among which cyclodextrin complexation is predominant. β-cyclodextrin was used since this possess a special ability to complex with drugs enabling them to increase solubility, reduce bitterness, enhance stability and decrease ...

Experimental data on the structure and properties of melts and fluids relevant to water-melt interaction in hydrous magmatic systems in the Earth's interior have been reviewed. Complex relationships between water solubility in melts and their bulk composition [Al/Si-ratio, metal oxide/(Al + Si) and electron properties of metal cations] explain why water solubility in felsic magmas such as those...
