Final answer:
In an electrochemical cell, steel can replace copper depending on the specific cell. The conductivity of steel is not as good as copper, so it may not be suitable for all electrochemical cells. Additionally, steel can corrode easily in such cells.
Step-by-step explanation:
In an electrochemical cell, steel can replace copper depending on the specific cell. The conductivity of steel is not as good as copper, so it may not be suitable for all electrochemical cells. Additionally, steel can corrode easily in such cells, which makes it less desirable as a replacement for copper.
