How To Make Red Cabbage pH Paper Test Strips

How To Make Red Cabbage pH Paper Test Strips Its easy, safe, and fun to make your own pH paper test strips. This is a project that kids can do and that can be done from home, though calibrated test strips would work in a lab, too. Difficulty: Easy Time Required: 15 minutes plus drying time Heres How Cut a red cabbage (or purple) into pieces such that it will fit into a blender. Chop the cabbage, adding the minimum amount of water needed to blend it (because you want the juice as concentrated as possible). If you dont have a blender, then use a vegetable grater or chop your cabbage using a knife.Microwave the cabbage until its at the boiling point. Youll see the liquid boil or else steam rising from the cabbage. If you dont have a microwave, soak the cabbage in a small volume of boiling water or else heat the cabbage using another method.Allow the cabbage to cool (about 10 minutes).Filter the liquid from the cabbage through a filter paper or coffee filter. It should be deeply colored.Soak a filter paper or coffee filter in this liquid. Allow it to dry. Cut the dry colored paper into test strips.Use a dropper or toothpick to apply a little liquid to a test strip. The color range for acids and bases will depend on the particular plant. If you like, you can construct a chart of pH a nd colors using liquids with a known pH so that you can then test unknowns. Examples of acids include hydrochloric acid (HCl), vinegar, and lemon juice. Examples of bases include sodium or potassium hydroxide (NaOH or KOH) and baking soda solution. Another way to use your pH paper is as a color-change paper. You can draw on pH paper using a toothpick or cotton swab that has been dipped in an acid or base. Tips If you dont want colored fingers, soak only half of the filter paper with the cabbage juice, leaving the other side uncolored. Youll get less usable paper, but you will have a place to grab it.Many plants produce pigments that can be used as pH indicators. Try this project with some of the other common home and garden indicators.

Customer extension is offered via their site and e-mails. Amazons business model is now considerably more flexible as it has diversified from books and CDs to a range of products more typical of a department store. (Chaffey, 2004.)
