In this experiment, students will design and carry out a sequence of chemical reactions for the separation and identification of three metal cations from six unknown samples.

This site from Georgia State University discusses the precipitation reactions and deals with the lead iodide product. Links are provided to information on double replacement reactions as well as ionic compounds. Not too in-depth, this is...

Svante Arrhenius was born in Vik, Sweden, and became the first native of that country to win the Nobel Prize. The award for chemistry was bestowed to him in honor of his theory of electrolytic dissociation. Arrhenius also developed the...

This site explores the classification of igneous rocks. Content addresses classification based on color and texture, mineral composition, and chemical composition.

In this lesson plan, students learn about the components of air and the chemical reactions that release carbon dioxide into the atmosphere and explore the connection between carbon dioxide, climate change, and environmental health.

Presents a general overview of fuel cells including what is a fuel cell, how do they work, and the different types.

In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students...

Expand your knowledge of Chemistry. Observe how ionic compounds are networks of electrically charged atoms.

Georgia State University provides a technical discussion on how voltaic cells produce an external electric current. Equations for the reactions that occur are given and discussed.

In this module you will be able to test your understanding of how light energy is converted into different forms of chemical energy during photosynthesis, to review the equations for the light reactions of photosynthesis, and to explore...
