Redox is a leading distributor of chemicals and ingredients, active in more than 1,000 specialty and commercial products. Some metals can be considered to be more “active” than others, in the sense that a more active metal can replace a less active one from a solution of its salt. Zn … Zn + O2 + HCl ® ZnCl2 + H2O 2) Balance this redox reaction using the half-reaction method. CuCl 2 is an oxidizing agent, Zn is a reducing agent. To identify a chemical reaction as an oxidation-reduction reaction. Write the balanced, equation for zinc metal. Since the oxidation state of the chlorine doesn't change, do you just write out a line for the hydrogen, i.e., H^+ + e^- = H2? 39�E!��.�=OkN�m�oM��eO����-P��M�W��_ ��Y
