Chem 6C – Manual corrections 12.1d: the solution manual is correct but the back of the book is not. They have incorrectly written the dichromate ion as Cr 2 O 4 2- instead of Cr 2 O 7 2- . The coefficients are correct if it is written correctly. Some cell diagrams are not written correctly – pairs of ions should be written in order Ox, Red. (pg. 452). 12.11b: Should be Pt(s)/I 2 (s)/I-//Ce 4+ , Ce 3+ /Pt(s) 12.11d: Should be Pt(s)/Au 3+ , Au + //Au + /Au(s) 12.13c: Cell diagram should be written as Cd(s)/Cd(OH) 2 (s)/OH - (aq)//OH - (aq)/Ni(OH) 3 (s)/Ni(OH) 2 (s)/Ni(s). 12.26b: Pt(s)/Cr 3+ , Cr 2+ // I 3 - , I - /Pt(s) 12.33b: The number of electrons transferred should be n=1 not n=2. Thus the K = 1x10 2 12.46b: When calculating the Ksp you don’t have a value for n, because the reaction is not a redox reaction. Instead you have a value for nE = -0.35 V. Thus the answer should be 10 -6 . 12.56b: The answer should be 11.2 L. The solution manual uses 298 K as the temperature instead of the specified temperature of 273 K.
