19. According to the following reduction potentials which sentence is INCORRECT? Sn²"(aq) + 2e –→Sn(s) Fe2* (aq) + 2e →Fe(s) Zn2* (aq) + 2e →Zn(s) E° = -0.14 V E°= -0.44 V E°= -0.76 V * Fe is more easily oxidized than Zn. Fe acts as the anode and Sn as the cathode in the galvanic process. Sn is more easily reduced than Fe. Zn is the most powerful reducing reagent. Zn acts as the anode and Sn as the cathode in the galvanic process.
