Which of the following is/are the characteristics of a Galvanic series

1.	Which of the following is/are the characteristics of a Galvanic series?(a) Used only for pure metals(b) Less accurate prediction than EMF series(c) Includes active and passive potentials of a metal(d) Measured only at room temperatureThe question was posed to me by my school principal while I was bunking the class.This intriguing question originated from Principles in section Corrosion Principles of Corrosion Engineering
Answer» Correct option is (c) Includes active and passive potentials of a metal Best explanation: Galvanic series is the ARRANGEMENT of various engineering materials (pure metals and ALLOYS) in a decreasing reduction potential value in seawater. Galvanic series is more ACCURATE than EMF series and it can be measured at various temperatures of a specific MEDIUM. It includes the active state potential and passive state potential of a metal.
