A reducing agent is one of the reactants of an oxidation-reduction reaction which reduces the other reactant by giving out electrons to the reactant. Fluorine gas is known to be a strong oxidizing agent and whereas F- is said to be a weak reducing agent. This is the very definition of a good oxidizing agent. The amount of reducing agent dispensed is governed by the residual chlorine content. A) Co2+ B) Zn2+ C) Cd2+ D) Cu+ Thank You For The Help!! Metal hydrides, such as NaH, CaH 2, and LiAlH 4, which formally contain the H - ion, are also good reducing agents. Among the elements, low electronegativity is characteristic of good reducing agents. The two half reactions are the oxidizing reaction and the reduction reaction. &&\ce{Zn^2+ + 2 e- &-> Zn}\end{align}$$. and could you tell me the best reducing agent, and the worse? Still have questions? Why is hypochlorite a stronger oxidizing agent than other oxychlorides? Cr+3 is having least reducing potential, therefore Cr is the best Reducing agent. In the above reaction iron is losing 2 electrons thus, acting as a reducing agent. Fluorine should have the highest tendency to lose electrons, and hence should be the best reducing agent. Ans: When hydrogen ga… Flourine is the best oxidising agent because it has the highest electronegativity so it will reduce very easily. You have determined the correct oxidizing agent. 1 The classical conditions with hydride sources NaBH 4 in EtOH or LiBH 4 in THF have been applied to enantiopure α-thiocyanatophosphonates in order to prepare the corresponding α-sulfanylphosphonates. Lithium is, therefore, the most powerful reducing agent. Best is Li worst is Na. What is the strongest reducing agent? Due to the smallest standard reduction potential, lithium is the strongest reduction agent. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Lithium is, therefore, the most powerful reducing agent. \textbf{Oxidising agents:}\\ Using your table or our chemical intuition, we can then decide which reduction or oxidation is the easiest. Is there a book about the history of linear programming? Chemistry. Similarly, the weaker the oxidizing agent than the more strong is the corresponding reducing agent as shown in the figure below. You will need to reverse the signs for the reduction potentials; the most positive of these will indicate the best reducing agent! Source(s): chemistry expirement question. The highest oxidizing agent is the weakest reducing agent. This is used in the analysis of copper(II) ions in solution. The glucose (C 6 H 12 O 6) is being oxidized, so it is the reducing agent. The more negative the value, the stronger reducing agent the metal is. The strongest reducing agent is : (A) F– (B) Cl – (C) Br – (D) I … It is a good idea to recap the the definitions of oxidation and reduction when approaching this kind of question, and also what it means to be an oxidising or a reducing agent: Oxidising is defined as the loss of electrons, reduction as the gain. The reduced atom is called the oxidizing agent; it takes electrons from the oxidized atom, which is another name for the reducing agent. Best reducing agent: Most easily oxidized: Most easily reduced: Oxidizing and Reducing Agent. The complex formation changes the colour of the absorbed light. Let’s understand it by an example of redox reaction – Image will be uploaded soon. Your email address will not be published. Take Zigya Full and Sectional Test Series. MathJax reference.
