Cited passages: Introduction, acetone–chloroform system; Procedure, Figure 1 caption and apparatus prose, Table 1, thermometer calibration, corrected pressure, stable-temperature reflux and paired samples; Abbé refractometer readout, pure-solvent and condensate agreement control and evaporation limitation; Table 2 caption and composition conversion; repeated additions paragraph and Results and Analysis. The apparatus caption and prose were inspected, but the apparatus photograph pixels were not. The handout specifies a procedure rather than a measured student dataset; its changing-temperature series is not a direct test of a fixed-temperature activity-coefficient relation.
