Also, a drug’s behavior in water and other aqueous systems can be studied to learn more about the chemistry of biological systems. Using an Anton Paar density and sound velocity meter, densities and sound velocities for CP (0–0.10 mol⋅kg⁻¹) at various temperatures (298.15, 308.15, and 318.15 K) in water and in aqueous 0.05 mol⋅kg⁻¹ urea, glucose, and sodium chloride have been measured to determine apparent molar properties: apparent molar volume (<span>(V_{phi} ))</span> and apparent molar compressibility <span>((K_{phi, {mathrm{S}}}))</span>. A number of derived parameters, including limiting apparent molar volume <span>(left( {V_{phi }^{0} } right))</span>, limiting apparent molar compressibility (<span>(K_{phi, {mathrm{S}}}^{0}))</span>, limiting apparent molar expansibility (<span>(phi_{mathrm{E}}^{0} ))</span>, and isobaric thermal expansion coefficient (<i>ɑ</i>) were obtained using the data on apparent molar properties. While analyzing the data, solute–solvent interactions are taken into account, as well as their considerable effects on CP hydration when co-solutes, are introduced to the combination. The negative transfer properties suggest the predominance of ion-hydrophobic and hydrophobic-hydrophobic interactions in all the studied systems. Positive and small negative values of Hepler’s constant revealed the structure-making capability of CP in aqueous urea, glucose, and sodium chloride. Also, an IR study has been done to verify the results obtained from volumetric and compressibility data. Understanding how drugs behave in various solvent systems during drug development is made easier by understanding drug interactions.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 3","pages":"449 - 470"},"PeriodicalIF":1.4,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138688960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether solvent shared ion pairs and the direct contact ion pairs exist in aqueous LiCl solutions or not, and the details about these ion pairs are still under debate.

Using this method, the hydration spectra of Cl⁻ in LiCl, NaCl, and KCl aqueous solutions were measured from the diluted concentration to the highly concentrated solution. Hydration number of Cl⁻ from the hydration spectra was determined to be ~ 2 in the aqueous LiCl. These data demonstrated that about 3–4 Li⁺ replaced some water molecules in the first hydration shell of Cl⁻. As the concentration of LiCl increased, an abnormal increase in the hydration number was observed. This is because the water molecule that bridges Li⁺ and Cl⁻ in the solvent-shared ion pair are particularly stable, which was directly proven by the red shift of the hydration spectra of Cl⁻ in the O–H stretching region. All the hydration spectra and hydration numbers not only applied to uncover the solvent shared ion pairs and direct contacted ion pairs in LiCl aqueous solution, but also can be employed to the benchmark of force fields in the classical molecular dynamics simulations.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 3","pages":"431 - 448"},"PeriodicalIF":1.4,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138524359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
