For the battery shown below: -1 F 2 + 2 e (1) Label the anode and cathode. (2) Circle a cation. (3) Put a triangle around an anion. 2 F + 2. 85 V +2 -1 Hg 0 + 0. 85 V +2 -1 Cu 0 + 0. 34 V +2 -1 Zn 0 - 0. 76 V +1 -1 Na 0 - 2. 71 V Hg + 2 e (4) Label each electrode with material it is made of. - Cu + 2 e Zn + 2 e Na + 1 e A negative ion Zinc metal Cathode Cupper metal Anode A positive ion from one type of a metal A positive ion from a different type of metal A “Daniell Cell” design battery from U-betch-em Company Not a cation in this redox reaction. Just because you are positive does not mean you get to be a cation. (You have to get involved with a cathode!!)

For the battery shown bellow: (1) Label the anode and cathode. (2) Circle a cation. (3) Put a triangle around an anion. -1 F 2 + 2 e 2 F - + 2. 85 V +2 -1 Hg 0 + 0. 85 V +2 -1 Cu 0 + 0. 34 V Hg + 2 e Cu + 2 e (4) Label each electrode with material it is +2 -1 0 Zn + 2 e Zn - 0. 76 V made of. (5) For this battery, write the +1 -1 0 - 2. 71 V Na + 1 e Na (a) The half reaction that occurs at the cathode. +2 -1 0 Zn + 2 e + 0. 76 V Zn (b) The half reaction that occurs at the anode. (6) What is the nominal voltage rating for A negative ion this battery? + 0. 34 V + (+0. 76 V) = 1. 10 V Zinc metal A positive ion from Cathode one type of a metal Cupper metal Anode A positive ion from a different type of metal A “Daniell Cell” design battery from U-betch-em Company Not a cation in this redox reaction. Just because you are positive does not mean you get to be a cation. (You have to get involved with a cathode!!) “We guarantee that our batteries always work before you buy them”
