Part 4.—The Erdey-Grúz experiment. Relative solvent transport numbers for ion constituents in mixtures of water with raffinose, glycine, allyl alcohol, dimethylsulphoxide and dioxan","abstract":"Erdey-Grúz's diffusion experiment has been used to obtain the sum of the transport numbers of water by ions, relative to a second solvent component, Σn°w=(n+)°w+(n–)°W. The theory of the experiment is described in detail; the corrections for the effect of salt on solvent activity, lacking in Erdey-Grúz's work, have been made. The experimental method involved a diaphragm cell and analysis of changes in mixed-solvent concentration by interferometry.The Σn°w are combined with Washburn numbers, w°w, some of which are new values obtained from cells with ion-selective electrodes. With w°w=(n+)°wt+–(n–)°wt–, the ionic n°w are obtained unambiguously for systems containing low concentrations of glycine, allyl alcohol, dimethylsulphoxide (DMSO) and dioxan. These data were also calculated for a 0.75%(w/w) raffinose + water mixture using transport and diffusion data from the literature.The n°w values for the raffinose + water system, which probably approach closely the dynamic solvation number, N, of the ion in pure water, are Li+(16), Na+(10), K+(6), Cl–(4) and H+(1). In the remaining systems these figures are reduced by the competition of the organic molecule for solvation of the ion. In the glycine + water system the ions transport glycine preferentially.","is_dataset_classified":null,"base_score":2.639057329615259,"endowment":2.639057329615259,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W2082257802","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.13978833,"influential_citations":0,"citation_trend":[{"year":2013,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"http://pubs.rsc.org/en/content/articlepdf/1982/F1/F19827801431","host_type":"publisher"},{"url":"https://doi.org/10.1039/f19827801431","host_type":"journal"}],"fields_of_study":["Analytical Chemistry and Chromatography","Spectroscopy and Quantum Chemical Studies","Molecular spectroscopy and chirality"],"mesh_terms":[],"keywords":["Chemistry","Solvent","Ion","Salt (chemistry)","Alcohol","Diffusion","Glycine","Analytical Chemistry (journal)","Chromatography","Organic chemistry","Thermodynamics","Amino acid","Biochemistry","Physics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-05T10:47:30.994140Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
