This paper lab takes the form of worksheet to help students with the challenges surrounding compounds containing polyatomic ions. A table of common polyatomic ions is provided for convenience.
Students identify the positive and negative ions by name and formula. Then they use the "charge crossing" strategy to find the formula of the compound. Lastly, they sketch the compound and name it using standard IUPAC rules.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
