Chem 1061 1st Edition Lecture 9 Outline of Last Lecture I Titration II Oxidation Reduction Reactions Redox a Ionic b Covalent c Oxidation d Reduction e Oxidizing agent f Reducing agent g Oxidation number III Using Oxidation Numbers to Identify Redox Reaction Outline of CurrentLecture IV Elements in Reduction Oxidation Reactions a Combination b Decomposition c Displacement i Double Displacement ii Single Displacement iii Activity Series d Combustion V Reversibility of Reactions These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute Current Lecture Elements in Redox Reactions atom element in one side and compound on the other TYPES 1 Combination a X Y Z b Where either X or Y or both is an element One ALWAYS has to be an element 2 Decomposition a Z X Y b Where X or Y or both are elements Again one HAS to be an element 3 Displacement single a There is double displacement These are the precipitation and acid base reactions we did where the partners were swapped This is NOT a redox reaction AB CD AD CB b Single displacement IS a redox reaction An atom of one element displaces the ion of another It is common in metals i X YZ XZ Y c Activity Series in Metals i Metals are ranked by their ability as reducing agents ii Any metal can reduce a metal lower on the list iii LIST IS FIGURE 4 24 IN TEXTBOOK iv Example Zinc cannot displace copper but copper can displace zinc 4 Combustion a Combines with oxygen b Usually producing heat and or light c Most common is fuel burning with O2 gas to produce CO2 g and H2O g Reversibility of Reactions Equilibrium state Will cover this EXTENSIVELY in Chem 1062 There is NO net reaction Common in weak acids and bases which dissociate slightly For Chem 1061 only worry about FORWARD reactions
