168.What is electrochemical series? What are its important applications?
We know the reducing power of a metal depends on upon its tendency to lose electrons. Thus, lower the reduction potential, more the tendency to get oxidised and thus more will be the reducing power. Hence increasing order of reducing power of metals is, Ag < Hg < Cr < Mg < K.
