Exploring the pH dependent aqueous speciation of metal complexes through UV-Vis spectroscopy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Coordination chemistry is a major component of the undergraduate inorganic chemistry curriculum and yet the presentation of the material can be cumbersome due to the limitations of the course typically being taught in one semester. Also, because of the large scope of this branch of chemistry encompassing all of the elements, the course design has not been standardized. These factors result in some important coordination chemistry themes being given insufficient development. Herein we propose a novel activity to formally introduce metal complex aqueous speciation in a holistic active-learning manner that includes a lecture component and hands-on experience. This topic has real world relevance and contextualizes many important coordination concepts. It would extend student comprehension about the intricate factors that affect metal complexation in an aqueous solution environment by focusing on the influence of pH. The activity explores the pH dependent speciation of the well-characterized interaction between Fe(III) and 2,3-dihydroxynapthalene-6-sulfonate and reveals the colorful changes in species throughout the pH range of 0 to 13. Students learn how to generate speciation plots and to understand the ultraviolet-visible (UV-Vis) electronic absorption spectroscopy of transition metal compounds to be able to analyze the source of color that they observe. Assessment of the activity was conducted with 24 students who completed a Likert scale survey and responded to open-ended questions. The activity was then applied in actual course settings in which student comprehension was quantitatively evaluated. The activity can be easily adapted to students of different stages of academic development from elementary to college students.
