Ap Chemistry Redox - Basic Flashcards

9696875171	Reduction	The gain of electrons	0
9696875172	Oxidation	The loss of electrons	1
9696875173	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
9696875174	Electrochemical Cell	Any device that converts chemical energy into electrical energy or electrical energy into chemical energy	3
9696875175	Voltaic Cell	in which a spontaneous chemical reaction produces a flow of electrons( +G)	4
9696875176	Electrolytic Cell	cell that requires an electric current to force a chemical reaction to occur (-G)	5
9696875177	Electrode	The site at which oxidation or reduction occurs in an electrochemical cell	6
9696875178	Anode	The electrode in which Oxidation occurs	7
9696875179	Cathode	The electrode in which Reduction occurs	8
9696875180	Salt Bridge	In a voltaic cell, a ___________ connects the two containers and provides a path for a flow of ions between the two beakers.	9
9696875181	Electrolysis	When electricity is used to force a chemical reaction to occur	10
9696875182	LEO says GER	LEO: Loss of Electrons is Oxidation GER: Gain of Electrons is Reductions	11
