The spectrophotometric determination of the percent composition of an aspirin tablet is a common first-year, general chemistry undergraduate laboratory procedure. The experiment requires that a known amount of pure acetylsalicylic acid be quantitatively converted into the soluble disodium salicylic acid that is further reacted with excess…

The design and operation of the vapor-absorption refrigerator (VAR) are described using the principles and tools typically covered in upper-division undergraduate physical chemistry courses. The objective is to enable students to understand in detail how this device works and how it compares with more typical vapor-compression refrigerators.…

Keto-enol tautomerism is a fundamental concept that examines the migration of a proton between two constitutional isomers, the keto and enol tautomer. Many experiments have been proposed to understand the concept behind Meyer's Rule, which states that the keto tautomer is favored as the solvent polarity increases. However, all the experiments have…

During their first year of study at university, many students encounter challenges in developing learning strategies that align with success in the courses in which they are enrolled. The emergence of the COVID-19 pandemic heightened the challenges as universities were compelled to transition to online learning. Therefore, this study investigated…

Our organic chemistry course enrolls students from the medicine major. As future healthcare professionals, medical students should also take on the responsibility of publicizing scientific knowledge related to human health. Therefore, starting from 2020, we have designed an assignment that tasked students with writing a popular science essay for…

We present the development and evaluation of "da Vinci's Curse", a chemistry escape room experience designed to consolidate laboratory skills in a fun and interactive setting. Inspired by the maestro, Leonardo da Vinci, the escape room challenges students to complete a series of puzzles in teams to escape "da Vinci's Curse".…

Purpose: Although technology is a defining characteristic of distance education, assessment of the applicability of such resources in knowledge dissemination is greatly warranted to ensure effectivity. Hence, the purpose of this study was to assess the viability of a novel tool in teaching practical chemistry online. Design/methodology/approach:…

Chemical spillage has been measured for undergraduate students undertaking a laboratory practical designed to help develop their chemical handling skills. There was a low correlation found between the amount of chemical spilled and the ability to accurately carry out the primary goal of the experiment, which was to measure the concentrations of…

RAMP is an acronym for the process "recognize hazards, assess risk, minimize risk, and prepare for emergencies". This paper describes these four steps in the context of undergraduate instruction about chemical health and safety.

Green chemistry provides unique opportunities for student engagement through K-12 and community outreach. As a platform for safe, engaging outreach, green chemistry activities allow for hands-on approaches to introducing science and chemistry concepts in informal settings. Green chemistry outreach also is a means for American Chemical Society…

Educational resources that cover essential knowledge related to chemistry safety rules are openly accessible on the CHIMACTIV website (http://chimactiv.agroparistech.fr/). Organized into two online tracks, the content covers personal and collective protections, first aid, as well as the handling of hazardous chemicals. Being interactive and…

This study aimed to learn more about the results of the research on the chemical literacy ability of junior high school students in South Sulawesi based on atomic, ionic and molecular materials. The samples in this study were Public Middle School 6 Makassar, Public Middle School 2 Maros and Public Middle School 4 Sinjai. Samples were taken…

One of the most widely used solutions to fix and preserve organic tissues is formaldehyde, despite reservations regarding its toxicity and the fact that formaldehyde-embalmed bodies lose their original characteristics. Anatomy laboratories have been replacing formaldehyde with solutions that retain the characteristics of fresh tissue. For this…

Purpose: The emerging field of educational data mining provides an opportunity to process large-scale data emerging from higher education institutions (HEIs) into reliable knowledge. The purpose of this paper is to examine factors influencing persistence amongst students enrolled in a Chemistry major at a South African university using enrolment…

Interactive molecular dynamics in virtual reality (IMD-VR) simulations provide a digital molecular playground for students as an alternative or complement to traditional molecular modeling kits or 2D illustrations. Previous IMD-VR studies have used molecular mechanics to enable simulations of macromolecules such as proteins and nanostructures for…
