Ch. 18 Galvanic Cells

True or false: in a galvanic cell, the anode is the positive electrode.

False

True or false: in a galvanic cell, the negative ions in the salt bridge migrate into the anode beaker.

True

What is teh anode

the negative side

What is the cathode

the positive side

Which direction does the flow of e- travel

from anode to cathode

What does a single | mean in shorthand

phase change

What does a double || mean in short hand

salt bridge

What goes first in short hand

anode

Is the anode the rduction or oxidation

oxidation =

is teh cathode reduced or oxidized

reduced

What do you add if you need an inner elctrode

Pt(s)

What flows out of the anode beaker

e-

What flows into the anode beaker

a negative salt

What flows into the cathode beaker from the salt bridge

a positve salt

What flows into the cathode beaker from the charge

e-

How do you calculate the E of the cell

Ecell = E cathode - E anode

is a E + likely to reduce or not

reduce

Are larger E + more likely to to reduce or less

more

Are E - likely to reduce or not

un-likely

What charge on E is spontaneous

+

What charge on E is non-spontaneous

-

How do you predict from shorthand what will be reduced or oxidized

Whichever has a larger + charge is reduced

How do you relate E to G

G = -nFE

what is n

the amount of mols of e transfered

What is F

96,500 c/mol e-

If E is +, what is G

negative
