Which of the following are the limitations of the EMF series?(a) Avail

1.	Which of the following are the limitations of the EMF series?(a) Available for metals and alloys(b) Limited to pure metals only(c) Measured only at standard conditions(d) Limited to pure metals and measured only at standard conditionsThis question was addressed to me in an online interview.The question is from Eight Forms in section Eight Forms of Corrosion of Corrosion Engineering
Answer» The correct option is (d) LIMITED to pure metals and measured only at standard CONDITIONS The explanation: EMF series is a LIST of pure metals arranged according to their electrode POTENTIAL value measured against SHE. It is measured at standard conditions such as 25°C, 1atm pressure, and 1M concentration of hydrogen ions.
