It is expected that a chemical reaction will occur when copper metal is combined with aqueous zinc sulfate. Explain why there will be no reaction when zinc metal and aqueous copper sulfate solution are combined. Identify the anode and the cathode, assuming a voltaic cell is constructed. Note: Be careful in the calculation of the standard cell potential ( Eo cathode - Eo anode). Do not change the sign of the given reduction potential. The sign is already taken care...

1. Write a balanced chemical equation for the oxidation of zinc metal (Zn) by copper(II) ions (Cu?") in a copper sulfate solution. Note that copper(II) sulfate completely dissociates in aqueous solution and forms Cu2+ (aq) and SO,- (aq) in water. Zinc metal is a solid and should be represented as Zn (3) Write a chemical equation for the decomposition of limestone (CaCO,) by heating to high temperature to drive off carbon dioxide.

2. Copper(I) sulfate forms a bright blue solution in water. If a piece of zinc metal is placed in a beaker of aqueous CuSO4 solution, the blue color fades with time, the zinc strip begins to erode, and a black solid forms around the zinc strip. What is happening? Write half-reactions to show the chemical changes that are occurring. What will happen if a piece of copper metal is placed in a colorless aqueous solution of ZnCl2?

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−
