An Activity Series—College Level Classic General Chemistry Laboratory Kit

Product Details

College Level Classic General Chemistry Experiment Students study a series of metals and nonmetals to determine their relative reactivity, then rank them according to their reactivity in an activity series. First, the reactivity of the metals is determined by reacting a series of metals with metal salt solutions. Then, the reactivity of the halogens is determined by reacting each of the halogens with a halide solution. Based on the observed reactivity in each case, students develop a separate activity series for the metals and the halogens. Students understand why some metals can "replace" other metals, and why some redox reactions are spontaneous while others require a battery. Students also learn that the reactivity for the halogens is opposite that for the other families in the periodic table. Complete for 24 students working in pairs.
