During lockdown a homeowner had to call out a plumber to fix water pipes. The plumber did not want to directly connect a galvanized steel pipe to a copper pipe, but rather suggested using an insulated fitting to connect them to avoid corrosion. Explain whether you agree with the advice using your knowledge of electrochemistry/corrosion/spontaneous reactions. Discuss possible spontaneous reactions that might occur and cause the corrosion. You may support your answer with standard emf calculations.

Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
