General chemistry classes practice spectroscopy. They grasp the relationships between wavelength, absorbance, and solution concentration. Additionally, they gain valuable practice using laboratory equipment such as burets and pipettes....

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Emerging chemists find their calling as they calculate the concentration of hydronium and hydroxide ions and the pH and pOH for several solutions. In some cases, values are given, and in others, actual word problems are written out....

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Students choose a variety of design elements to create playing squares for a challenging matching game of Concentration. They distinguish matching patterns, numbers, and colors as they test their memories. Studnets hone skills and...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

In this making standard solutions worksheet, students read about the process of making a standard solution and perform 3 background calculations necessary to make standard solutions. Students then make a solution by weighing a given...

In this acid and base learning exercise, students calculate the concentration and pH of solutions. This learning exercise has 7 problems to solve.

Young scholars discuss the difference between concentration and solubility as well as examine the difference in a hands-on activity. Using water and table salt, they experiment with solubility. They create different concentrations using...

Young scholars observe demonstrations that illustrate the amount of alcohol in various drinks and how it is distributed in the body. They discover the effects of alcohol on the brain due to its high water content. They calculate alcohol...
