Safety Notice: It is okay to taste the mystery powder this time because your teacher knows what they are. However,
you should NOT go around tasting mystery substances without knowing what they are. Discuss why with your partner.
Solubility Test: If a powder is soluble, it dissolves completely in water. Test each mystery powder by stirring a small
amount into the water and observing what happens. Did it dissolve completely or can you still see the substance?
