Question

qualitative analysis in Polarography is based upon
a) electrode potential
b) half wave electrode
c) migration current
d) limiting electrode​

Answer 1

Answer:

(a)electrode potential

Explanation:

3Principle  The principle in polarography is that a gradually increasing negative potential (voltage) is applied between a polarisable and non-polarisable electrode and the corresponding current is recorded. ...  Thus, polarography can be used for both qualitative and quantitative analysis of compounds.
