Redox Flashcards

4571289149	Reduction	The gain of electrons	0
4571289150	Oxidation	The loss of electrons	1
4571291844	Oxidation Numbers	Indicates the number of electrons lost, gained, or shared as a result of chemical bonding. Higher: Less electrons/less negative Lower: More electrons/more negative	2
4571293398	Oxidizing Agent	Accepts electrons and becomes reduced.	3
4571293399	Reducing Agent	Donates electrons and becomes oxidized.	4
4571295451	Half Reaction	An equation that shows either oxidation or reduction, including the amount of electrons lost or gained.	5
4571296882	Electrochemical Cell	Any device that converts chemical energy into electrical energy or electrical energy into chemical energy	6
4571296883	Voltaic Cell	An electrochemical cell in which a spontaneous chemical reaction produces a flow of electrons	7
4571298249	Electrolytic Cell	An electrochemical cell that requires an electric current to force a chemical reaction to occur	8
4571298250	Electrode	The site at which oxidation or reduction occurs in an electrochemical cell	9
4571298251	Anode	The electrode in which Oxidation occurs	10
4571299347	Cathode	The electrode in which Reduction occurs	11
4571299348	Salt Bridge	In a voltaic cell, a ___________ connects the two containers and provides a path for a flow of ions between the two beakers. This makes a complete circuit and allows for a reaction.	12
4571300548	Electrolysis	When electricity is used to force a chemical reaction to occur	13
4571302330	LEO says GER	LEO: Loss of Electrons is Oxidation GER: Gain of Electrons is Reductions	14

4571375255	Hydrogen	+1 in compounds unless combined w/ a metal, when it is -1	16
4571378816	Oxygen	Usually -2 but combined w/ fluorine it is +2 and in a peroxide (O2 or H2O2) it is -1	17
4571393405	Sum	The ____ of the oxidation numbers in all compounds must be 0 The ____ of the oxidation numbers in polyatomic ions must be equal to the charge of the ion	18
