Additional reactions such as reactions with acids, displacement reactions, or reactions with other reactive substances can help establish the order of reactivity among metals like zinc, iron, copper, and lead. These reactions provide clearer indications of the relative reactivity of these metals compared to each other.

Displacement reactions with acids can help establish the order of reactivity among metals like zinc, iron, copper, and lead. More reactive metals, such as zinc and iron, readily displace hydrogen from acids, producing metal salts and hydrogen gas. Copper, being less reactive, may undergo such reactions under specific conditions and with strong acids. Lead, being relatively unreactive, typically does not readily displace hydrogen from dilute acids. These displacement reactions provide valuable insights into the relative reactivity of metals, helping to establish an order based on their ability to displace hydrogen ions in acidic environments.
