就是这句话的解释:ionic compounds are often soluble in water because water is a polar molecule and is attracted to the ions.要的是解释不是翻译(不是很理解“water is a polar molecule and is attracted to the ions” 相关知识点: 试题来源: 解析 由离子构成的分子,遇水会进行离子的游离,与水中的H...
If, on the contrary, intramolecular forces are stronger, it is not soluble or sparely soluble. The solubility of ionic compounds The basic guideline is: Ionic compounds are soluble. The more ionic, the more soluble, since the interaction between ions and solvent (usually water) is strong enou...
CONSTITUTION: A soluble ionic complex comprises pharmaceutically effective ionicpolypeptides selected from hedgehog protein, bone developing protein, growth factor, EPO, TPO, G-CSF, interleukin or interferon, and additionally, zwitter compounds such as anionic or zwitterionic hydrophobic surfactant, phosphoric...
Theionic strengthof the medium will impact both the crystalline and amorphous solubility with higherionic strengthsolutions being expected to reduce solubility. It may be difficult to detect the effect of ionic strength on the crystalline solubility for very poorly water soluble compounds due to small...
We first succeeded in synthesizing ionic liquids from 20 natural amino acids. Amino acid ionic liquids dissolved native amino acids, despite water-free conditions. Furthermore, these ionic liquids are soluble in various organic solvents, such as chloroform. Effects of acidity, hydrogen bonding ability...
The same compounds under the same conditions were reacted at a ratio of cyclopexo-15 crown-5 to Li(Tf)2N of 1:1.35. No loss of mass was observed during vacuum rotary evaporation at 100° C. for four hours. Both products were soluble in organic solvents including acetone and acetonitrile...
Only in 1934, a patent described the use of liquid state quaternary ammonium salts as processing aids for cellulose [22]. Indeed, their ability to dissolve a wide variety of organic substances or to be used in liquid-liquid extraction have led to be considered for processing poorly soluble ...
The obtained neutral compounds were highly soluble in organic solvents; however, they were insoluble in water. Therefore, the DMSO-H2O mixture was used to test the stability of the complexes. In the last studies, the synthesis and physicochemical characterization of the vanadium(V) complex with ...
In one embodiment of the invention, Q1 and Q2 are both H. Alkylated aromatic compounds have many industrial uses, including as intermediates in styrene production, cumene production and surfactant synthesis. The production of at least one alkylated aromatic compound is carried out by a process compr...
Imipramine hydrochloride (IMP) is a white to off-white, practically odorless, crystalline powder, soluble in water and in alcohol is freely (Scheme 1). Amitriptyline hydrochloride (AMT) consist of a rigid hydrophobic ring also an alkyl amine portion which turns out to be protonated at low pH...
