TL;DR: The earlier compiled self-consistent spectrophotometric basicity scale in acetonitrile (AN) was expanded to range from 3.8 to 32.0 pK(a) units, that is 28 orders of magnitude, and 54 new relative basicity measurements were carried out and 37 new compounds were introduced to the scale.

TL;DR: The self-consistent spectrophotometric acidity scale of neutral Brønsted acids in acetonitrile (AN) spanning 24 orders of magnitude of acidities is reported, and the structure-acidity relations are discussed.

TL;DR: In this article, the most important uncertainty sources that affect analytical UV-Vis spectrophotometric measurements are discussed, and eight uncertainty sources are discussed that are expected to have influence in chemical analysis.

TL;DR: In this paper, two uncertainty estimation approaches are presented and applied to the p K a values of the compounds on a previously established self-consistent spectrophotometric basicity scale in acetonitrile.

TL;DR: In this article, the authors describe the experience of working under an ISO 17025 compliant quality system in a university environment and describe the benefits for the university and the graduate students, concluding that implementation of an ISO-17025 compatible quality system is fully accomplishable and gives significant added value to the university by helping to destroy the ivory tower perception about universities and by introducing real-world flavour into the studies and broaden the minds (quality awareness) of the students.
