Question- A plumber's handbook states that you should not connect a copper pipe directly to a steel pipe because electrochemical reactions between the two metals will cause corrosion. What spontaneous redox reaction(s) might cause the corrosion? Justify your answer with standard emf calculations, please!
I am not able to determine the correct answer for the above question please helps me to get the correct answer
