This lab contains procedures for double and single replacement reactions. Most of the double replacement reactions involve noticeable precipitates. One of them will require the use of a centrifuge or time for the precipitate to settle enough to be noticeable. The single replacement reaction is an acid/metal reaction that produces hydrogen gas and can be tested with a burning splint.
Students make predictions about the reaction type based on the formulas of the reactants.
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.
