How do scientists identify an unknown solution? What makes one solution different from another? The experiments in this kit will help students understand the impact different chemicals have when added to a solution. Student will test the unknown solutions and determine the identity based on a comparison of the chemical properties to a known sample. Kit contains enough materials for 10 groups. Teacher’s manual and Student Study Guide copymasters are included.
