Question: Which of the following metals cannot be used as an anode in a galvanic cell?

Options:

Correct Answer: Copper

Solution:

Copper cannot be used as an anode in a galvanic cell because it is less reactive than zinc.

Which of the following metals cannot be used as an anode in a galvanic cell?

Which of the following metals cannot be used as an anode in a galvanic cell?

Step 1: Understand what an anode is. An anode is the electrode where oxidation occurs in a galvanic cell.
Step 2: Know that in a galvanic cell, the anode must be made of a metal that is more reactive than the other metal used in the cell.
Step 3: Identify the metals in the question. In this case, we are comparing copper and zinc.
Step 4: Learn about reactivity. Zinc is more reactive than copper, which means zinc can easily lose electrons.
Step 5: Conclude that since copper is less reactive than zinc, it cannot be used as an anode in a galvanic cell.
