Question

Difference between galvanizing and cathodic protection

Answer 1

Answer:

Sacrificial protection is a displacement reaction with the electrons travelling from the more reactive metal (Zinc) to the steel which reverses the oxidation process. Galvanization also provides sacrificial (Cathodic) protection to any small damaged areas where the steel substrate is exposed.

Answer 2

$\huge\mathfrak\color{blue}{Answer}$

Electromotive Force (EMF) has been measured to be 1.100 V. A concentration of 1 M in an ideal solution is defined as the standard condition, and 1.100 V is thus the standard electromotive force, DEo, or standard cell potential for the Zn−Cu galvanic cell
