Strong electrolytes NaCl and KCl significantly affect the solubility of the solute in the organic phase. The distribution coefficient of every solute increases with raising the amount of electrolyte. This salting-out effect is more pronounced for NaCl than for KCl. The effect may be particularly ...
Suggest reasons why the solubility of most solid substances in liquid solvents increases with temperature, whereas the solubility of gases decreases with temperature. Why can water dissolve many substances? Why is 70%-75% ethanol used for sterilization? What is the reason why hydrocarbons are not ...
The high concentrations of acetone in the solvent favor selectivity for furan compounds but difficult the solubility of the sugars The activity tests revealed different behaviors between acid catalysts employed, catalysts based on resins are more active, but the intrinsic activity (TOF) of silica-...
In which solvent would cyclohexane have the lowest solubility, 3-pentanol, diethyl ether, water, or octane? Which of the compound pairs below can be separated using the simple distillation technique? A. Acetone and Dimethyl sulf...
Which one of the following is a poor aprotic solvent for an SN2 reaction? A) CH3SOCH3 (DMSO) B) CH3OH C) C6H6 D) CH3COOH E) CH3CN The solubility of salicylic acid in diethyl ether is 1 g / 3 mL at 25 degree C. Is diethyl ether an appro...
SolubilityThorium(IV)Equilibria in the system of Nd(III) and Th(IV) with 8-hydroxyquinoline (oxine), thenoyltrifluoroacetone (HTTA) and 1,10-phenanthroline (phen) in 5.0 m NaCl solution have been investigated by spectroscopy and potentiometry. The solubility and deprotonation constants of the ...
In which solvent would cyclohexane have the lowest solubility, 3-pentanol, diethyl ether, water, or octane? Which of the following compounds will be most soluble in nonane (C9H2O)? a. 1-pentanol b. benzene c. ethanol d. ethyl methyl ketone e. acet...
Arrange the compounds in order of decreasing solubility in water. (a) 1-hexanol (b) 1, 2-hexanediol (c) Hexane Rank the compounds in order of increasing polarity (1 = least polar, 3 most polar). A) i. ii. iii. Rank the following substanc...
With regards to the change in selectivity, one should consider that we are working in a biphasic media and thus the catalyst hydrophilic character, as well as the relative solubility of reactants and products both in toluene and water, is important. Active sites in the catalyst will probably ...
(Figure 5). Acetone vapor has a high solubility in water [31]. The decrease in acetone-elimination capacity of BTF could be related to the increase in the dissolved acetone concentration in the nutrient solution over time, which subsequently caused the decrease in its solubility capacity in the...
