  5. When a piece of copper metal is put into a solution of silver nitrate (AgNO3), silver metal is produced along with Cu2+, the latter of which is responsible for the blue color of the solution. Which of the following statements is false? 1. DG for the reaction is negative (the reaction is exergonic). 2. For every mole of Cu reacted, two moles of Ag is produced. 3. Cu is oxidized. 4. Ag is an oxidizing agent. 5. A solution of CuSO4 will be blue.
