What is the process of galvanizing in chemistry and how does it work to protect metal surfaces from corrosion?

Galvanizing is a process in chemistry where a protective layer of zinc is applied to metal surfaces to prevent corrosion. This is done through a method called electroplating, where the metal surface is coated with a thin layer of zinc through an electrochemical reaction. The zinc acts as a sacrificial anode, meaning it corrodes before the underlying metal does, thus protecting the metal surface from rust and corrosion.
