A negative standard reduction potential for a particular species means that is easier to reduce H + than to reduce that species. A positive standard reduction potential for a species means that it reduces more easily than H +.Since chlorine has a higher reduction potential than iron, at the cathode, reduction of chlorine occurs, and at the anode, oxidation of iron occurs. E o cell = 1.36 -(-0.440) = 1.80 volts The positive value of E 0 Cell implies that the reaction occurs spontaneously.That means the compound has also become a better oxidising agent through photoexcitation. We can estimate how much the reducing or oxidizing power of a compound changes upon excitation by a photon. For example, the reduction potential depends upon the relative energy level of the orbital into which an electron would be donated.Risk avoidance deals with eliminating any exposure to risk that poses a potential loss, while risk reduction deals with reducing the likelihood and severity of a possible loss. This article will ...If the standard reduction potential of lithium is very negative, then the oxidation potential of lithium ion is very positive. If it is uphill to transfer an electron from hydrogen to lithium cation, it must be downhill to transfer an electron from a lithium atom to a proton. After all, hydrogen is more electronegative than any of the alkalis.Since Strongest oxidising agent means it has greater tendency to oxidise other species and itself gets easily reduced. So higher the E 0 values, stronger is the oxidising agent it is. Thus, A g + having highest positive E 0 value among the given systems, is the strongest oxidising agent.Electrochemical series is defined as the arrangement of the elements or their ions in increasing or decreasing order of their standard electrode potential under standard conditions.
