Standard 3 Objective 2
1 class periods of 90 minutes each
Students will practice making and recording observations about various compounds and their aqueous solutions, write the formulas for the compounds, then perform chemical reactions and write the names and formulas of the products.
See MSDS or the chemical container for precautions for each chemical. Some compounds in this lab are toxic, skin irritants, caustic, etc. Small enough quantities are used, however (two drops of each solution for each reaction), that the reactions plates can be rinsed with excess water down the drain. Use safety goggles and aprons.
ways of observing, writing names of ionic compounds from formulas and vice-versa (Note: It is not necessary that students be familiar with writing reactions and predicting products, as the ions that will react in each case are designated for them, and they only need to combine these ions.)
Before class, prepare 100 mL of 0.1 M solutions of each of the following: (If you have dropper bottles to dispense these solutions into, you can fill 2 dropper bottles (50 mL each) of each solution, and the preparations should last a couple of years, at least.)
