Science from Scientists: Chemical Identification
In this lesson, students will perform several experiments to determine the identities of four different household white powders (baking soda, cornstarch, chalk and a mystery powder) based on their solubility in water and simple chemical reactions with acetic acid and iodine.
After the testing, students will learn how to distinguish between physical and chemical properties of substances and how these can be used to identify substances.
