Question

A Zn atom on the electrode loses 2 e- which join the collection of delocalized electrons on the metal. What is the reaction for this event? Is this an oxidation or a reduction? Examine figure 1(c) closely. Three microscopic processes are shown. One is characterized by movement of delocalized electrons to a zinc ion. Two others show the loss of electrons by a Zn atom. Label the oxidation and reduction processes in figure 1c. Key Questions A strip of zinc metal is placed in a solution of Zn(NO2)2 and equilibrium is established. Note: Nitrate ions and water molecules are omitted for clarity. 5. Draw arrows to show where the electrons are going as equilibrium is reached. Confirm that the drawing shows that oxidation is the favored reaction. 6. Describe the microscopic processes that occur when a strip of zinc metal is placed in a solution of Zn[NO 3 7. Which of the following reactions occurs to a greater extent? Explain your reasoning.
