ocr: -7- CH111 FINAL 1985 PAGE7 47. Ptis (a) Oxicized at the anode (b) reduced at the anode (c) oxidized at the cathode (d) reduced at the cathode - 48. Calculate E cell' (a) 2.7Y (c) 0.3Y (b) -0.3V (d) -2.7V 49. - An electrochemical cell is constructed in whichone electrode is made of nickel, immersed in a IM Nita solution, and the other is made of iron, immersed in a IM Fe+3 solution. The standard reduction potential for nickel is -0.250V, and that for iron is -0.036Y. Ifthe ni electrode is negative, the cell reaction is: (a) - 2Fe * 3N1" +2,5*3. - 3A: (c: 2Fe*3 - 3Ni : 2Fe + 341*2 (D) 2Fe*2 Ni*2 ...
