The oxidizing agent is the reactant which does the oxidizing and therefore, contains the element reduced. And the reducing agent is the reactant which does the reducing and therefore, contains the...Identify the substances that are oxidized and reduced, and indicate which is the oxidizing agent and which is the reducing agent. Solution. Analyze: We are given a redox equation and asked to identify the substance oxidized and the substance reduced and to label one as the oxidizing agent and the other as the reducing agent. Plan:.. species reduced is the "oxidizing agent".. species oxidized is the "reducing agent" ***** the idea is REDOX (REDuction OXidation) reactions are all about electrons being transferred. Since electrons have a - charge, if a substance takes electrons from another, its charge must be going down.3 a redox reaction 1.

Sample Exercise 20.1 Identifying Oxidizing and Reducing Agents
Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrobromic acid (HBr) is mixed with an aqueous solution of lithium hydroxide (LiOH). Which substance is the oxidizing agent in the reaction 2CuO+C→2Cu+CO2 ? Ca + 2 HCl ---> CaCl2 + H2 B. H2 + Cl2 ---> 2 HCl C. NaCl + LiNO3An oxidizing agent in a chemical reaction is defined as that substance, which has the capacity to oxidize other substances by gaining electrons from them. In a chemical reaction, an oxidizing agent is usually reduced by gaining electrons. In the chemical equation given above, iron ll oxide oxidizes carbon monoxide to carbon dioxide.A. Loss or gains of oxygen Oxidation: - combination of substance with oxygen Reduction: - removal of oxygen from substance Example: 2CuO + C 2Cu + CO2 CuO loses its oxygen to form copper. Carbon gains the oxygen to form carbon dioxide. CuO causes the oxidation of carbon. Carbon causes the reduction of CuO.Solution for Safari File Edit View History Bookmarks Window Help ) 47% Sun 11:03 AM session.masteringchemistry.com Consider summer class... Inbox (13) -…
Which substance in the reaction is the oxidizing agent
Reduced substance = MnO ₂ Oxidising agent = MnO₂ Reducing agent = HCl (b) 2H₂S + SO₂--->3S +2 H₂ O ( after balancing) Oxidised substance = SO₂ Reduced substance= H₂S Oxidising agent= H₂S Reducing agent= SO₂ (c) 2CuO + C ---> 2Cu ( after balancing) Oxidised substance = Cu Reduced substance= O₂ Oxidising agent= O₂ ReducingA reducing agent reduces another substance by giving it electrons. Therefore, by reducing the other substance, the reducing agent is itself oxidized. Therefore, in a reaction, the substance thatAnd here while copper (as Cu2+) is reduced, carbon is oxidized, 0 C → +IV C. The second reaction represents the reduction Cr(V I +) to Cr(I I I +) Cr2O2− 7 +14H + + 6e− → 2Cr3+ +7H 2O (ii) And the oxidation of ethanol to carbon dioxide:The oxidation state of hydrogen goes from 0 to +1. The oxidation state of oxygen is −2 and does not change in this reaction. In the process, CO2(g) is reduced to CO(g), and H2(g) is oxidized to H2O(g). The species that is oxidized, H2(g), is the reducing agent, and the species that is reduced, CO2(g), is the oxidizing agent.(1) 2CuO + C → 2Cu + CO2 In this reaction, oxidation number of C changes from 0 to +4. As oxidation no of C increases, C is oxidized from C to C4+. (2) 16H+ + 2Cr2O72− + C2H5OH → 4Cr3+ + 11H2O + 2CO2
Oxidation is an build up in the oxidation state, while relief is the lower in oxidation state. The oxidizing agent is the reactant which does the oxidizing and therefore, contains the part decreased. And the lowering agent is the reactant which does the lowering and due to this fact, contains the part oxidized.
..+2-2.........0 .............0 ........+4-2
2CuO(s) + C(s) --> 2Cu(s) + CO2(g)
Carbon is oxidized, and subsequently, C is the reducing agent.
Cu in CuO is decreased and due to this fact, CuO is the oxidizing agent.
