Gen Chem Chapter 11

Front 1

Oxidation

Back 1

Loss of electrons

Front 2

Reduction

Back 2

Gain of electrons

Front 3

Oxidizing Agent

Back 3

Causes another atom to undergo oxidation and is itself reduced (gains electrons)

Front 4

Reducing Agent

Back 4

Causes another atom to undergo reduction and is itself oxidized (losses electron)

Front 5

Common Oxidizing Agents

Back 5

Contain oxygen or a similarly electronegative element

Front 6

Common Reducing Agents

Back 6

Contain metal ions or hydrides (H-)

Front 7

Oxidation Number- Free Element

Back 7

Number of zero

Front 8

Oxidation Number- Monatomic Ion

Back 8

Equal to the charge on the ion

Front 9

Oxidation Number- Metals in Compounds

Back 9

Group IA: +1, Group IIA: +2

Front 10

Oxidation Number- Group VIIA in Compounds

Back 10

Number of -1 (unless combined with an element of higher electronegativity)

Front 11

Oxidation Number- Hydrogen

Back 11

+1 unless paired with a less electronegative element in which case it is -1

Front 12

Oxidation Number- Oxygen

Back 12

+2, expect in peroxides (-1) or in compounds with more electronegative elements

Front 13

Half-Reaction Method

Back 13

1. Separate two half-reactions

2. Balance the atoms by adding H and O (acidic: water and H+, basic: water and OH-)

3. Balance the charges by adding e-

4. Multiply half reaction to even out number of electrons

5. Add half reactions and cancel out terms on both sides

Front 14

Complete Ionic Equation

Back 14

Accounts for all of the ions present in a reaction. To write split all aqueous compounds into their relative ions

Front 15

Net Ionic Equations

Back 15

Ignore spectator ions (ions appearing on both sides of the reaction)

Front 16

Specific Net Ionic Equations

Back 16

Reaction with no aqueous salt: same as overall balanced reaction. Double displacement without solid salt formation: no net ionic equation

Front 17

Disproportionation Reactions

Back 17

Redox reaction in which one element is both oxidized and reduced forming at least two elements with different oxidation states

Front 18

Oxidation-Reduction Titration

Back 18

Titrations that follow the transfer of charge with indicators that change colors based on voltages of the solution

Front 19

Potentiometric Titration

Back 19

Redox titration where a voltmeter or external cell measures the electromotive force of a solution
