In this unit, we continue the discussion of solutions, but specifically concentrate on a special type of solutions, acids and bases. Concepts from previous units will include chemical formulas and equations, calculating molarity, and naming compounds. If you have forgotten some of these concepts, you may wish to review them now. As always, you will need your periodic table and scientific calculator handy.

In this module, you will complete a lab at your home, and the following will be required:

• red cabbage
• blender or knife
• boiling water
• filter paper (coffee filters work well)
• one large glass container
• six small glass containers or jars
• household ammonia (NH₃)
• baking soda (sodium bicarbonate, NaHCO₃)
• washing soda (sodium carbonate, Na₂CO₃) Found in the laundry aisle of your local grocery store, Arm & Hammer is a common brand.
• lemon juice (citric acid, C₆H₈O₇)
• vinegar (acetic acid, CH₃COOH)
• cream of tartar (potassium bitartrate, KHC₄H₄O₆)
• antacids (calcium carbonate, calcium hydroxide, magnesium hydroxide)
• seltzer water (carbonic acid, H₂CO₃)
• drain cleaner if available (be careful, this is caustic and will burn your skin)
