Isentropic compressibility and viscosity of aqueous and methanolic lithium chloride solutions
Bibliographic record
Abstract
Densities, speeds of sound, and viscosities of aqueous and methanolic lithium chloride solutions were measured as functions of concentration, m (mol kg 1 ) (0.3911 [Formula: see text] m [Formula: see text] 19.47) and temperature (273.15 [Formula: see text] T [Formula: see text] 323.15 K). Measured values of the density, speeds of sound, and viscosity agree well with previously reported data. The isentropic compressibility isotherms for the aqueous solutions converge at a particular concentration, in the temperature range of the study, providing crucial information regarding the solvation behaviour of the ions. However, for the methanol solutions, the isentropic compressibility isotherms decrease smoothly with concentration and converge on extrapolation. Anion solvation controls the viscosity processes at low temperatures whereas cation solvation controls the same at high temperatures. Total primary solvation numbers of lithium chloride in water and methanol were estimated to be 6.0 and 1.9, respectively.Key words: lithium chloride, speeds of sound, viscosity, isentropic compressibility, solvation number.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
