Redox Reaction

oxidization decrement Redox Reaction Chapter 6 attainment Objectives after(prenominal) completing this chapter, students should be able to: Define redox answer, oxidizing serving and reducing cistron. key out the oxidizing agent and the reducing agent. cypher the oxidisation number. Write the balanced redox reaction by ionelectron method. 2 oxidisation Reaction Redox Reaction involves the reduction and oxidisation of the reactants, Examples: rusting of metal, the chemical reaction inside a battery, and combustion of hydrocarbons. The reaction occur when a snapper catch oxygen, unload electron and increase in oxidization number. Reduction Reaction The reaction occur when a substance lose oxygen, gain electron and decrease in oxidation number. 3 4 1 Oxidation-Reduction Reactions (electron transfer reactions) 2Mg2+ + 4e- Oxidation half(a)-reaction (lose e-) O2 + 4e2O2Reduction half-reaction (gain e-) 2Mg + O2 + 4e2Mg2+ + 2O2- + 4e5 2Mg + O2 2MgO 2Mg 6 Write the half reactions of the following reaction. Then, Identify the oxidizing agent and the reducing agent. Exercise 6.

1 Identify the oxidizing agent and reducing agent in the following reaction: Zn (s) + CuSO4 (aq) Zn Zn2+ + 2e- Zn is oxidized Cu2+ + 2e- ZnSO4 (aq) + Cu (s) Zn is the reducing agent Cu Cu2+ is reduced Cu2+ is the oxidizing agent 4Al ? 3O 2 ? 2Al 2 O 3 Copper wire reacts with pieceic number 47 nitrate to framing silver metal. What is the oxidizing agent in the reaction? Cu (s) + 2AgNO3 (aq) Cu Ag+ + 1eCu2+ + 2e- Cu(NO3)2 (aq) + 2Ag (s) Ag+ is the oxidizing agent 7 Ag Ag+ is reduced 8 2 Oxida tion emergence The level the atom would h! ave in a molecule (or an noggin compound) if electrons were all told transferred. 1. Free elements (uncombined state) have an oxidation number of zero. Oxidation Number (cont.) 3. The oxidation number of oxygen is usually 2. In H2O2 and O22- it is 1. 4. The oxidation number of hydrogen is +1 except when it...If you indigence to look at a full essay, order it on our website: OrderEssay.net
