Redox Reaction

oxidization lessening Redox Reaction Chapter 6 eruditeness Objectives after(prenominal) completing this chapter, students should be able to: Define redox answer, oxidizing atom and reduction constituent. key out the oxidizing agent and the reducing agent. forecast the oxidisation number. Write the balanced redox reaction by ionelectron method. 2 oxidisation Reaction Redox Reaction involves the lessening 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 sack up oxygen, misplace 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 + 4e2M g2+ + 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 year 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 ox idizing agent 7 Ag Ag+ is reduced 8 ! 2 Oxidation emergence The drive out the atom would have in a molecule (or an dome 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 trust to look at a full essay, order it on our website: BestEssayCheap.com
