Ionic vs. Covalent Bonding
An interactive comparison between ionic, non-polar covalent, and
polar covalent bonds. (flash-based)
Chemical Bonding & Molecular Structure: This
powerpoint presentation explains bonding and molecular
structure. It explains VSEPR modeling as well.
CHEMICAL BONDING AND COMPOUND FORMATION
This site investigates the types of chemical bonds, ways to
predict compositions and the conventions of naming the
Types of Chemical Bonding: This
site offers information on how to determine the different types
of chemical bonds.
Differences Between Ionic & Covalent Compounds: Students
will observe some of the differences in macroscopic properties
between ionic and covalent compounds. In particular, they
compare solubility in water, solubility in methanol, relative
melting points, and solution conductivity.
The Tyndall Effect
video clip illustrates the Tyndall effect as a means of
distinguishing a solution from a colloid.
Signed With a Kiss (A Chromatography Lab): This
experiment (presented in a powerpoint presentation) uses paper
chromatography to determine the identity of a lipstick sample.
It brings a little forensics/real world application into the
DNA Simulation with Paper Chromatography: This
activity is a mock electrophoresis using paper chromatography.
following page contains links to tutorials that are PowerPoint
Chemodules that emphasize various topics in Solutions. Each
includes basic concepts and learning checks to test student
Colligative Properties of Solutions: This
lab uses environmentally safe antifreeze to allow students to
investigate colligative properties of solutions. Can be adapted
to use with probeware.
Colligative Properties Animation: This
flash animation allows students to change solvent & solute,
change the amounts added, as choose a hot water or cold water
bath to investigate colligative properties. Values obtained can
then be used in calculations. This is a good animation to show
your classes or as an alternative to an actual lab.
