Give the standard electrode potentials: K+/K = -2.93 V, Ag+/Ag = +0.80 V, Cr+3/Cr = -0.74 V Out of these electrode which will be the strongest reducing agent? Share with your friends Share 0 Vartika Jain answered this Dear Student, An electrode with lesser value of standard electrode potential is better reducing agent and that with higher value of standard potential is better oxidant.Amongst the given ions, K+/K has the least value of electrode potential, and so it will be the strongest reducing agent. 0 View Full Answer
