Chemical Formula Lab

In this lab you will practice writing the formulas of various ionic compounds. You will also make and observe different ionic compounds. There are nine different solutions available. You can mix any two which you feel will make an ionic compound. To do this, place 2-3 drops of the first solution on the overhead, then add 2-3 drops of the second solution onto the first solution.

Lab Writeup
