QUESTION 5 1 points A voltaic eelis setup with asiver electrode Use the reduction potentials table inthe notes/book. What is the reaction occuring What is the reaction occurring at the What the potent the coLE points Save Answer The value for reaction What is the value E for 3c QUESTION 7 1 points save Anewer Using the reduction potential table form the bookhotes which ofthe following solids wilmact wth amHa solution consider Haas astrong acid aq 7 voltaic celissetup with an ion electrode in a nitate solution and acopper electrode copper Use the reduction potentials table in thenotes/book. What reaction occurring at the anode AE +011V What the reaction occuring at the cell GEeel -0.11V

Explanation / Answer

Q5 nickel act as anode and silver act cathode

       Ni(s) ----------> Ni+2 + 2e-      E0 = 0.23V at anode oxidation

      2Ag+ + 2e- ------> Ag(s)          E0 = 0.80V at cathode reduction

------------------------------------------------------------------------------------

                                                      E0   = 1.03V

Q7.A + B ------> C      E0 = 0.88V

      3C -------> A+ B   E0 = -0.88V

Q7

O2 stron oxidicing agent

Q8 2Al + 6HCl --------> 2AlCl3 + 3H2

Q9 iron act aa anode and copper act as cathode

     Fe-------------> Fe+2 + 2e-    E0 = 0.41V   at anode oxidation

    Cu+2 + 2e- --------> Cu(s)    E0 = 0.34Vat cathode reduction

-----------------------------------------------------------------------

                                                   E0cell = 0.75V
