P.E. Elective 6 4.2 "Exploration of Chemistry Problems Around You" ppt Teaching material: zinc-copper-dilute sulfuric acid as the primary battery Special task: theoretically analyze whether aluminum-copper-sodium hydroxide can be used as a material to form a primary battery. Basic requirements: Through the primary battery experiment, deepen the understanding of the working principle of the primary battery. Development requirements: According to the known total reaction formula of the battery, the positive and negative electrodes of the battery can be judged and the electrode reaction formula can be written. Note: The effect of the polarization of the electrode on the current generated by the primary battery is only a general understanding. Class hours arrangement: 1 class hour, (total 2 class hours, the production of hydrogen-oxygen fuel cell and hydrogen evolution corrosion, oxygen absorption corrosion will be placed in the second class hour)
