Using Ion Exchange Chromatography to Separate Proteins

In this ions activity, students complete a table by combining the given ions in different combinations to make a neutrally charged chemical compound.

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

In this charge and electricity instructional activity, students read about electric charges and how they are created in atoms. They also read about the unit of charge, called the Coulomb, conductors, and insulators. Emerging electricians...

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Four pages provide plenty of problem solving practice for chemistry whizzes. They answer questions and write electron configurations for ions. They use Lewis dot diagrams to display equations. Covalent bonds are explored. The last half...

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Advanced techniques for the lab use of chromatography are detailed here and your students will learn the specifics of separating molecules using a staionary and mobile medium. Diagrams of the equipment used and some facts about how...

Lead the way in naming polyatomic ions and have fun at the same time. Pupils learn the rules for naming polyatomic ions, primarily oxyanions. They learn patterns to determine the charge of an ion and when to add a hydrogen molecule to an...

A few basic facts about lattice energy are listed at the top of the page, including the formula used for calculations. Two charts follow: one for lattice energy and another for ion sizes. There is no work to do on this handout, but it...

Teaching intermolecular forces can be quite a stretch! Chemistry scholars experiment with the attractive strength between polar molecules using an interactive resource. Learners test molecules of low, medium, and high polarities by...
