1.	Polarographic cells type of electrochemical method uses which of the following concepts?(a) Cyclic reactions(b) Exothermic reactions(c) Reversible reactions(d) Redox reactionsThis question was posed to me in an internship interview.I'd like to ask this question from Electrochemical Methods for Oxygen Analysis topic in chapter Industrial Gas Analysers of Analytical Instrumentation
Answer» Correct option is (d) Redox reactions To explain I would say: Polarographic cells type of electrochemical METHOD USES redox reactions. It is USED to measure the partial pressure of the PERCENTAGE of oxygen.
