A student fills one small vessel with 1.0 M Cu2+ and another with 0.10 M Zn2+. A piece of filter paper saturated with sodium sulfate is used for a salt bridge. What should the student use for the electrodes?
any neutral electrodes will work
a copper electrode in the Zn2+ and zinc in Cu2+
a copper electrode in the Cu2+ and zinc in Zn2+
any metal if they're both the same metal
Homework Answers
ANSWER:
a copper electrode in the Cu2+ and zinc in Zn2+
EXPLANATION:
These are the metal electrodes, the metal electrodes are constructed by dipping the metal in the solution which containing the respective metal ions. Hence
copper electrode is constructed by dipping the copper metal in the solution containing Cu2+ ions.
Zinc electrode is constructed by dipping the Zinc metal in the solution containing Zn2+ ions.

In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
