Charleston Law, CHEMISTRY 112
Excerpt: ... CHEM 112 TEST FOUR - MAR 28, 2003 - Page 1 Name (please print): _ Allow two consecutive hours (but not at a time when you have another scheduled class) for taking this test. You may use your personal hand-calculator and your Blue Sheet of Standard Potentials LECTURE: Multiple choice 33 pts. (3 pts each) For each question, choose the BEST answer and write the letter in the left margin next to the question. 1. When a piece of Zn is placed into a solution of CuSO4, a reaction is seen to occur. The explanation for this occurance is that The zinc redox couple is a stronger oxidizing agent than the copper redox couple The reduction potential for the copper redox couple is higher than that for the zinc redox couple Zinc is oxidized to Zn2+ because itll have a smaller reduction potential as determined from the Nernst equation The zinc redox couple is the better reductant in this system All of the above 3 of the above 2 of the above a) b) c) d) e) f) g) a) b) c) d) 2.

CHM exp report 9
Abraham Baldwin Agricultural College, CHEM 130
Excerpt: ... and the precipitate, CuS are used to change the concentration of Cu2+(aq) in the Cu2+/Cu redox couple. The observed changes in the cell potentials are interpreted by using Le Chatelier's principle. Besides, the Nernst equation is applicable to redox systems that are not at standard conditions, most often when the concentration of the ions in solution are not 1 mol/L. In Section C, the cell potentials for a number of zinc/ copper redox couples are measured in which the copper ion concentrations are varied but the zinc ion concentration is maintain constant. ...

Excerpt: ... ferent oxidation states d) present only while a redox reaction is occurring and does not exist otherwise e) two of the above 11. When a solution of CuSO4 has added to it a piece of Zn metal, a reaction occurs. The explanation for the reaction is that a) The Cu+2 - Cu reduction potential is higher than that for the Zn+2- Zn. b) The copper redox couple is a better oxidizing agent than the zinc redox couple c) Zn+2 is poorer at taking on two electrons and becoming Zn than Cu+2 is in becoming Cu. d) The Nernst equation gives a lower value for the zinc couple than it will for the copper couple e) All of the above f) only 2 of the above = -3100 KJ Chem 112, Test 4 - March 29, 2002 - page 3 12. Given 2 redox couples, A+3, A+2 and X+4, X+2 What, if anything, is needed to produce a half cell? a) nothing is needed in either case; you already have a redox couple b) to act as the appropriate electrode you also need the species in the zero oxidation state in each case; that is, metallic A, and metallic X c) to act as ...
