Supercooling to the Max

By Nüsret Hisim Water is an obvious choice when studying phase change because students regularly encounter phenomena that involve water. While data-collection technology helps students visualize what is happening to the temperature as water cools, the process occurs through a blurry, ice-filled beaker. For my students, the temperature increase of the ice/water mixture in the…

Reactivity of the Alkaline Earth Metals

It can be challenging to find a safe wet lab activity that demonstrates the periodicity of common periodic properties. In this International Year of the Periodic Table, try incorporating a conductivity probe, such as our versatile , to help students visualize data. For the experiment, students follow this simple procedure: Place 5 mL of distilled…

Understanding Nernstian Behavior Using Ion-Selective Electrodes

Use Vernier ion-selective electrodes (ISE) in an innovative way to facilitate student understanding of Nernstian behavior. While most ISEs on the market allow you to report measurements as potential (in mV), with our Go Direct® Ion-Selective Electrodes, you have the option to report readings in mg/L, mV, or both. Simultaneously displaying graphs of concentration and…

Conductometric Titration: An Alternative to Gravimetric Analysis

Gravimetric analysis is a classic technique for determining the mass of an analyte through precipitation. Because of the complex nature of gravimetric analysis, it can be a challenging experiment. In an article published in the Journal of Chemical Education, Jennifer Garcia and Linda Shultz compare a conductometric titration to conventional gravimetric analysis and conclude that…

Explore Vitamins with New Features of Spectral Analysis

Vitamin B2, also known as riboflavin, was first isolated in 1933. It is an essential nutrient for humans as the precursor of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). FAD plays a key role in several important enzymatic reactions in metabolism, including the Krebs cycle. Riboflavin also happens to be a relatively…

Discover the Wavelength

Many schools can’t afford a classroom set of spectrophotometers. So how can you use a single spectrophotometer and a class set of colorimeters to have your students discover the best wavelength of light to use in an experiment? For Beer’s law and kinetics experiments, students must choose a specific wavelength to conduct the experiment. Students…

Forensic Chemistry: Analysis of a Mystery Powder

As part of the investigation of a crime scene, detectives note that a white powder is found at the location. Even though they have their suspicions, chemical and physical analyses must be performed to determine the identity of the powder. That’s where the crime scene technicians take over. Melting graph for unknown mystery powder from…

Spotlight on New Inquiry Based Experiment for Spectroscopy

Are you interested in spectroscopy but don’t know where to begin? You are in luck! We’ve recently designed a new experiment, “A Guided Inquiry Approach to Understanding Fluorescence Spectroscopy,” to help students understand what goes on inside the “black box” of a spectrophotometer. This experiment, which can be done with either or our , has…
