We're being asked to rank the given species from strongest to weakest reducing agents. Reducing agent is the species that are being oxidized in a redox reaction. Recall the mnemonics LEO GER. L oss E lectrons → O xidation → Reducing Agent Strong reducing agents are weak oxidizing agents. Sodium, hydrogen, and lithium are examples of strong oxidizing agents. While weak reducing agents cannot lose electrons easily. Fluorine, chlorine, iron etc. are weak reducing agents Of these species—H 2 O 2 (aq), Zn(s), I − (aq), Sn 2 + (aq), identify which is the strongest reducing agent in aqueous solution and thus the best candidate for a commercial product. From the data in Table \(\PageIndex{1}\), suggest an alternative reducing agent that is readily available, inexpensive, and possibly more effective at removing. The permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4-ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4-ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good.
Why is fluorine gas the strongest oxidizing agent and fluoride ion is the weakest reducing agent? Fluorine gas is the strongest oxidizing agent because of these factors:- Very high electron gain enthalpy (2nd highest to be specific) Low bond dissociation enthalp The weakest reducing agent (strongest oxidizing agent) would be the element that would be easily reduced or most likely to gain an electron. 88% (57 ratings

(Hint: Remember that reducing agents get oxidized.) Question 5: The strongest oxidizing agent is said to have the most positive potential and th This page explores the trend in oxidising ability of the Group 7 elements (the halogens) - fluorine, chlorine, bromine and iodine. We are going to look at the ability of one halogen to oxidise the ions of another one, and how that changes as you go down the Group
The reducing character of the hydrides of Group 15 elements increases from NH 3 to BiH 3 (Bismuthine) because the reducing character depends upon the stability of the hydride.The greater the unstability of anhydride,the greater is the its reducing character.Since,the BiH 3 is the least stable (because the size of central atom is greatest & therefore its tendency to form stable covalent bond. The bigger the number, the stronger the reducing agent. For example, among Na, Cr, Cu and Cl −, Na is the strongest reducing agent and Cl − is the weakest one. Common reducing agents include metals potassium, calcium, barium, sodium and magnesium, and also compounds that contain the H − ion, those being NaH, LiH, [2] LiAlH 4 and CaH 2 Zinc is the agent for the reduction of something else, in this case, copper 2+ ions. So zinc is the reducing agent. Copper 2+ is gaining those two electrons, so copper 2+ is being reduced, but because copper 2+ is gaining those two electrons, it allows zinc to be oxidized. Copper 2+ is the agent for the oxidation of zinc Are metal ions always oxidizing agents? Metals themselves are solid materials, some hard, other soft that will act as reducing agents. The metal ions are the oxidized form of the metal atoms and act as oxidizing agents They have already lost electrons and therefore have a positive charge, and still have a relatively low electronegativity.
