Priya Yadav; Harshita Laddha; Madhu Agarwal; Ragini Gupta – Journal of Chemical Education, 2022
A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

Johnson, Ray L. – Journal of Chemical Education, 1982
A laboratory computer system based on the Commodore PET 2001 is described including three applications for the undergraduate analytical chemistry laboratory: (1) recording a UV-visible absorption spectrum; (2) recording and use of calibration curves; and (3) recording potentiometric data. Lists of data acquisition programs described are available…

McCarrick, Thomas A.; McLafferty, Fred W. – Journal of Chemical Education, 1984
Background, procedures used, and typical results are provided for an experiment in which students carry out the necessary measurements on the acid-catalysis of penicillin in two hours. By applying kinetic theory to the data obtained, the reaction pathways for the hydrolysis of potassium benzyl penicillin are elucidated. (JN)
