Question

define emf and emf series

Answer 1

electromotive force series - a serial arrangement of metallic elements or ions according to their electrode potentials determined under specified conditions; the order shows the tendency of one metal to reduce the ions of any other metal below it in the series.

Answer 2

HERE IS UR ANSWER
_________________^_^
EMF: An electromotive force series (EMF series) is a metal's ranking in respect to inherent reactivity. The metals located at the top of the series are considered the most noble, with the highest level of positive electrochemical potential. The metal that can be found at the bottom is the most active and contains the highest amount of negative electrochemical potential.

EMF SERIES : Electromotive force series - a serial arrangement of metallic elements or ions according to their electrode potentials determined under specified conditions; the order shows the tendency of one metal to reduce the ions of any other metal below it in the series.
