coordination compounds

Just the other day within my IB Chemistry HL classes, we were discussing the color of transition metal complex ions in solution. It's a bit imperfect, because they are not yet dissolved, but I set up a number of metal chloride salts in order to help students see the pattern.

The purpose of this unit is to acquaint you, the student, with some research techniques and to involve you in the discovery learning process. You will be given a topic to work on and some guidelines for what you should accomplish. You will work in groups of three and share your results with the other members of your group.

This laboratory exercise accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions.
