Given that the standard electrode potentials (E°) of metals are :
K+/K = -2.93 V, Ag+/Ag = 0.80 V, Cu2+/Cu = 0.34 V,
Mg2+/Mg = -2.37 V, Cr3+/Cr = -0.74 V, Fe2+/Fe = -0.44 V.
What is the increasing order of their reducing power?
Answer & explanation
Correct answer: option 2
More negative the value of standard electrode potentials of metals is, more will be the reducing power.
