Question

Data analysis: write the net ionic equations for any reactions that occurred between the metals and metal ions list occurred with N.R. Indicate any combinations where no reaction ed below (section la). e Lead ion and zinc . Lead ion and copper Zinc ion and lead . Zinc ion and copper . Copper(II) ion and lead . Copper(II) ion and zinc 2. In your notebook, write the net ionic equations for the react tions that occurred between the metals and HCI (section lb). Indicate any combinatio N.R. ns where no reaction occurred with H' and lead . H' and zinc H' and copper In your notebook, write the net ionic equation for the reaction of Cu with Ag' (section 1c). 3. 4. In your notebook, construct a table of standard reduction half-reactions for the reactions tested in section 1 (lead ion, zinc ion, copper(II) ion, hydrogen ion, and silver ion). Write the half-reactions as reductions, eg. M2+ + 2e-→ M. The half-reaction with the largest reduction potential (strongest oxidizing agent) will be at the top, followed by the remaining half-reactions in order of decreasing reduction potential. See Table 18.1 in your textbook (p. 873, Tro, 3d ed) for a model of what this table should look like. You don't need to include values of E in your table. 5. Write the net ionic equations for any reactions that occurred between the halogens and halide ions (section 2), or indicate any combinations where no reaction occurred with N.R . Chlorine and iodide ion Chlorine and bromide ion . Iodine and chloride ion lodine and bromide ion Bromine and chloride ion Bromine and iodide ion 6. Write the net ionic equations for any reactions that occurred between the Fe (section 3), or indicate any combinations where no reaction occurred with and hali Fe and bromide ion Fe3, and iodide ion net ionic equation for the reaction between the MnO; and chloride ion (section 4). 49 8. I your notebook, construct a table of standard reduction half-reactions for the reactions ted in sections 2, 3, and 4 (chlorine, iodine, bromine, Fe, and MnO4). Write the half tions as reductions, e.g. M2 +2eM. The half-reaction with the largest reduction potential (strongest oxidizing agent) will be at the top, followed by the remaining half- reacti reactions of E in your table. Write the net ionic equation for the reaction between bromine and copper (section 5). in order of decreasing reduction potential. See Table 18.1 in your textbook (p. 873, Tro, 3'd ed) for a model of what this table should look like. You don't need to include values 10 Using the table of standard reduction half reactions you generated in steps #4 and #8, as well as the data below, construct a new table of standard reduction half-reactions that includes all 10 half-reactions involved in this lab (lead ion, zine ion, copper(II) ion, hydrogen ion, silver ion, chlorine, iodine, bromine, Fe, and MnOa). The reaction with the largest reduction potential (strongest oxidizing agent) will be at the top, followed by the remaining reactions in order of decreasing reduction potential. Again, see Table 18.1 in your textbook (p. 873, Tro, 3nd ed) for a model of what this table should look like. You don't need to include values of E" in your table. Additional data needed to complete the table are in step #9 and listed below: a. Silver metal reacts with bromine. b. Ag' is a better oxidizing agent than 12. c. Copper metal reacts with Fe3+ d. Silver metal will not react with Fe3+ l2 is a better oxidizing agent than Cu2 48 Section in Oxidizing Attempt to the oxidizing agent If reaction occurred.
