Cu/Fe Galvanic Cell

When drawing a cell notation for a copper versus iron cell, what charge does iron go to?

• It does not change

• 1+

• 2+

• 3+

In the copper-iron galvanic cell, which metal gains electrons?

• Neither

• Copper

• Iron

• Both

What is used as a salt bridge in the described galvanic cell?

• Sodium chloride

• Potassium chloride

• Lithium nitrate

• Magnesium sulfate

Which direction do electrons flow in the described galvanic cell?

• From copper to iron

• Electrons do not flow

• In a circular motion

• From iron to copper

What is the result of copper gaining electrons in the galvanic cell?

• Iron turns into copper

• Copper electrode gets smaller

• Iron electrode gets smaller

• Copper turns into iron

What happens to the iron electrode in the galvanic cell?

• It gains electrons and increases in size

• It loses electrons and decreases in size

• It gains protons and increases in size

• It remains unchanged in size

What is the purpose of the salt bridge in a galvanic cell?

• To increase the voltage of the cell

• To decrease the voltage of the cell

• To allow the flow of ions and maintain electrical neutrality

• To prevent the flow of electrons between the electrodes

Which of the following statements is true about the galvanic cell involving copper and iron?

• The copper electrode acts as the anode

• The iron electrode acts as the cathode

• The copper electrode acts as the cathode

• Both electrodes act as cathodes
