RedoxReactions

Question 1

what is the pull or driving force on the electrons in a cell is called…

Answer 1

cell potential or electromotive force

Question 2

unit for electrical potential

Answer 2

voltage

Question 3

volt =

Answer 3

joule of work/coulomb of charge

Question 4

higher on the table will be ______, lower will be_______

Answer 4

reduction, oxidation

Question 5

E degrees symbol is the symbol for

Answer 5

standard cell potential.

Question 6

a positive standard cell potential means that the reaction is

Answer 6

spontaneous

Question 7

because the conventional notation is to write half reactions as reduction reactions, oxidation reaction standard cell potential must be

Answer 7

negated (flipped to opposite) when to equation is flipped

Question 8

REMEMBER TO BALANCE THE ELEMENTS BEFORE WRITING THE FRICKIN ELECTRON. aLSO, REMEMBER, THE NUMBER MATTERS IN THE CHARGE.

Answer 8

REMEMBER TO BALANCE THE ELEMENTS BEFORE WRITING THE FRICKIN ELECTRON. aLSO, REMEMBER, THE NUMBER MATTERS IN THE CHARGE.

Question 9

use of a salt bridge

Answer 9

permits the migration of IONS but does not allow the solutions to mix. this prevents charge build up.

Question 10

anode is

Answer 10

oxidized

Question 11

cathode is

Answer 11

reduced

Question 12

more reactive metals…

Answer 12

lose more electrons, are the ones being OXIDIZED

Question 13

in what direction do electrons flow

Answer 13

from anode to cathode, ie from the most active metal (the one being oxidized) to the least active metal.

Question 14

galvanic cell

Answer 14

a device in which chem. energy is changed to electrical energy spontaneously

Question 15

when a chemical cell has reached equilibrium, its charge is

Answer 15

zero

Question 16

corrosion

Answer 16

state of deterioration in metals caused oxidation or chemical action

Question 17

noble metals

Answer 17

metals like copper, gold, silver and platinum that are relatively difficult to oxidize

Question 18

rust is the ____ area

Answer 18

cathodic

Question 19

the nonmetal closest to the top of the Table J Activity Series is

Answer 19

most active, therefore most likely to be reduced

Question 20

the metal closest to the top of the Activity Series is

Answer 20

most likely to be oxidized

Question 21

electrolysis

Answer 21

the use of an electric current to bring about a chemical reaction

Question 22

in chemical (Galvanic) cells, the cathode is

Answer 22

positive, anode is negative

Question 23

in electrolytic cells the cathode is

Answer 23

negative, the anode is positive

Question 24

in electroplating, the object to be plated is the

Answer 24

cathode

Question 25

the material used for plating is the

Answer 25

anode

Question 26

the electrolyte used for plating is

Answer 26

a suitable salt of the metal that is the anode
