Final answer:The procedure that cannot be performed on a hot plate, requiring a Bunsen burner instead, is Performing aflame testfor metal ions (Option B).Explanation:A flame test formetal ionsinvolves heating a sample of a substance to be tested in the flame of a Bunsen burner. The characteristic color of the flame produced by the metal ions is used to identify the presence of specific metal ions. This procedure requires a Bunsen burner because it generates a hotter and more focused flame compared to a hot plate (Option B).A Bunsen burner provides a consistent, intenseflamethat is essential for producing the characteristic colors used in flame tests. On the other hand, a hot plate does not generate a flame but instead provides a heated surface, making it suitable for procedures like sterilizing laboratory equipment, heating a crucible, or conducting distillations. These other processes rely on heat transfer throughconductionand convection, rather than the open flame needed for a flame test.In a laboratory setting, it's crucial to use the appropriate equipment for each procedure to ensure safety, accuracy, and reliable results.Learn more aboutflame testbrainly.com/question/37837407#SPJ11...
