South Axholme School Page 4 Q12.Which one of the following can act as an oxidising agent but not as a reducing agent? It oxidises both metals and nonmetals. (iii) KMnO4 is a weaker oxidising agent than HCl. Among the following which is strongest oxidising agent. 9. Take another quick look at your list; all you have are neutral elements or the most common cations of said elements. Explains the trends in oxidising ability of the Group 7 elements in the Periodic Table by looking at their displacement reactions. Many other oxidizing agents are commonly used industrially as well as in the day-to-day lives of humans. The reducing agent, which is the opposite of the oxidizing agent, is the copper wire because it catalyzes the transfer of the electrons into hydrogen molecules. An oxidising agent is one that causes another substance to oxidise (i.e. Reason : Chlorine-carbon (C—Cl) bond in chlorobenzene has a partial double bond character due to resonance. Oxidative Phosphorylation One of the most important biochemical processes for all living animals is oxidative phosphorylation , or the transfer of … Of the four oxyacids of chlorine the strongest oxidising agent in dilute aqueous solution is [MP PET 2000] A) \[HCl{{O}_{4}}\] done clear Reducing agents Oxidation and reduction reactions play important roles in chemistry. Which of the following is the strongest oxidising agent? Name the oxidising agent in the reaction between Manganese dioxide and cone, hydro-chloric acid. Start studying Chapter 13 Micro Study Guide. Oxidising the different types of alcohols The oxidising agent used in these reactions is normally a solution of sodium or potassium dichromate(VI) acidified with dilute sulphuric acid. This can be explained by the following equation: 2Mg (s) + O 2 (g) → 2MgO (s) It can be seen that magnesium (Mg) reacts with oxygen (O2), and that oxygen is the oxidizing agent because it subtracts electrons from Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. Therefore it acts as an oxidising agent. following will convert [Mn(H 2 O) 6] 2+ into MnO A an acid and a reducing agent B an acid and an oxidising agent C an alkali and a reducing agent D an alkali and an oxidising agent (Total 1 mark) Q23.Which one of the following A Hot conc. Examples include household bleach (NaClO), Potassium Nitrate (KNO 3 ), and Sulphuric acid (H 2 SO 4 ). (d)€€€€ When HOCl acts as an oxidising agent, one of the atoms in the molecule is reduced. . (iv) KMnO4 acts as a reducing agent in the presence of HCl. A€€€€€€€an acid and a reducing agent B€€€€€€€an acid and an oxidising agent C€€€€€€€an alkali and a reducing agent D€€€€€€€an alkali and an oxidising agent (Total 1 mark) 5 Which one of the following could not act as a í 33 Therefore it acts both as oxidizing and reducing agent. The oxidising agent is the reactant that gets reduced. € € Atom that is reduced Tick (6) € €H € € €O € € €Cl € Page 8 of 81(1) Bromine is a fairly strong oxidising agent Iodine is the worst oxidising agent - mild The oxidising ability falls: as you go down the the group the atomic radius gets larger and there is an increase in shielding due to more inner shells of electrons - therefore there is a weaker attraction between the nucleus and the … (i) Both HCl and KMnO4 act as oxidising agents. Oxidising and Reducing Agents (1) Definition: The substance (atom, ion or molecule) that gains electrons and is thereby reduced to a low valency state is called an oxidising agent, while the substance that loses electrons and is thereby oxidised to a higher valency state is called a reducing agent. Learn vocabulary, terms, and more with flashcards, games, and other study tools. So, F 2 acts as a good oxidising agent. Hydrogen gas is a reducing agent when it reacts with non-metals and an oxidising agent when it reacts with metals. h2s+cl2=s+2hcl which substance is oxidized,reduced,oxidized agent - 1193040 As higher oxidation states of Mo and W are more stable, they will not act as oxidizing agent. For a substance to be an oxidising agent it must therefore be willing to The fact that the following reaction occurs, for example, suggests that copper metal is a stronger reducing agent than silver metal and that the Ag + ion is a stronger oxidizing agent … N goes from ON +5 to ON +2, so NO3- is the oxidising agent. Oxidizing Agent: The oxidizing agent is defined as the species that oxidizes another in a chemical reaction and undergoes reduction. Assertion : It is difficult to replace chlorine by –OH in chlorobenzene in comparison to that in chloroethane. Which is more reactive Mn o… Get the answers you need, now! Bromine can only oxidise iodide ions to iodine. So Nitrogen can get oxidized as wellas reduced. (ii) KMnO4 oxidises HCl into Cl2 which is also an oxidising agent. 0 0 Anonymous 1 decade ago NO3- is the oxidising agent. The oxidising power of oxy acids depends on its oxidation state.I.e. For a species to act as a reducing agent, it should have the ability to get oxidised. So, it s a weak reducing agent. A species can act as oxidizing agent only when metal ispresent in high oxidation state but lower oxidation state is more stable . It finds its uses as a weak oxidizing agent, disinfectant, and a bleaching agent. H 2 SO 4 into two gaseous products? In the following half equation, which is the oxidizing agent? Also, stronger the oxidising agent, weaker is its corresponding reducing agent. Spontaneous oxidation-reduction reactions convert the stronger of a pair of oxidizing agents and the stronger of a pair of reducing agents into a weaker oxidizing agent and a weaker reducing agent. The material meets one of the following conditions: For materials containing no more than 1.0 percent hydrogen peroxide, the available oxygen, as calculated using the equation in paragraph (a)(4)(ii) of this section, is not more than 1.0 percent, or asked Jan 25, 2019 in Class X Science by aditya23 ( -2,145 points) study of compounds hydrogen chloride (a) Br 2 (b) I 2 (c) Cl 2 (d) F 2 Answer/Explanation Answer: d Explaination: (d) F 2 is best oxidising agent. While in HNO2 the oxidation state of Nitrogen is +4. In chemistry, an oxidizing agent (oxidant, oxidizer), or oxidising agent (oxidiser) is a substance that has the ability to oxidize other substances — in other words to accept their electrons. NO3–(aq) + 4H+(aq) + 3e– NO(g) + 2H2O a. NO3– b. H+ c. e– d. NO e. H2O An oxidizing agent is a chemical compound that readily transfers oxygen atoms, or is a on Which of the following element is oxidised by conc. Which phenolic compound has commonly been added to soap and raises concerns about selection An oxidising agent is good at oxidising other compounds while being reduced itself; and vice-versa. Reason : Oxidising agent oxidises I 2 into HI. Balance the following ionic equations (i) Cr2O72- + H+ + I-→ Cr3+ + I2 + H2O (ii) Cr2O2-7 + Fe2 (i)€€€€€€Place a tick (6) next to the atom that is reduced. H 2 SO 4 acts as moderately strong oxidising agent. higher the oxidation state of chlorine stronger will be the oxidising power.Hence oxidising strength of oxyacids are in the following order: This is due to hhigh electron affinity of fluorine. Any element in its highest oxidation state, cannot oxidise anymore, and can hence not act as a reducing agent. Oxidising agent: 2Li(s) + H2(g) -->2LiH(s) hydrogen acts as an oxidizing agent because it accepts an electron donation from lithium, which causes Li to be oxidized. 20. Oxidizing agent: HNO3 In (iii) Oxidising agent: Fe2O3 Reducing agent: CO In (iv) Oxidising agent: O2 Reducing agent: NH3 26. Name the reducing agent in the following reaction : 3MnO2 +4 Al→3Mn + Al2O3. a. I2 b. MnO4-c. Zn2+ d. Zn e. MnO2 Answer Save 2 Answers Relevance Krrizh 1 decade ago Favourite answer MnO4- for sure!!!!! lose electrons), meaning that the agent itself will reduce (gain electrons). F 2 readily reduces to give F-.
