You will compare the reactivities of the metallic elements Na, K, Mg, and Ca to each other when they are added to water. You will need to get the instructor to help you because some of these elements react quite violently with water and require special precautions. So take the time now to observe the reaction of these four elements with water by doing the first part of exercise 10 in your workbook.
