Question

Help with labeling a diagram? :)

Answer 1

diagram! :)

Answer 2

Where does each of the following occur (Letter-wise)?

Cathode: D
Anode: ???
Battery: E
Where oxidation occurs: ???
Positive terminal: G
Negative terminal: H

***the ones where i put the letters are what i think it is, but i'm not very sure...

and i have no clue for anode and where oxidation occurs...

do y'all get this? :)

Answer 3

how do you say cathode is D?

Answer 4

Well, i dont think that cathode is D. Was it given initially that D is cathode or is it just according to you @iheartfood ?

Answer 5

because the cathode is the metal in the solution that sends electrons into the solution right?

but i'm not sure I'm looking at this diagram right haha :/ like i'm not really seeing it the right way ya know? ;/ I'm not interpreting it correctly :/

Answer 6

no, haha that was what i thought.. i mean i think i have the definition of cathode down correctly right?

but i'm not sure where that is applied in this diagram :(

Answer 7

Cathode is the metal "in the solution".... , is D present in the beaker or solution?

Answer 8

Check this it should help

Answer 9

oh.. no it isn't! so it has to be either F or C right? :)

Answer 10

Yep , good.

Answer 11

Well, can you say me, what is D now?

Answer 12

okay.. so based off that link, is F the cathode? And C is the anode?

Answer 13

yes, i heart

Answer 14

i'm not sure what D is haha :(

Answer 15

ooh! yay! :)

Answer 16

D is a conducting wire ... (or just a conductor ? :) )

Answer 17

so we have this so far now! :)

Answer 18

ohh okay i see... so i don't label D right? Cuz conductor isn't one of the things I'm labeling?

Answer 19

A could be flow of electrons

Answer 20

A trick for you to recognize anode and cathode : Cathode is much larger than anode.

Answer 21

electrons goes into the positive terminal of the battery

Answer 22

@iheartfood battery should be easy to idenitfy

Answer 23

ahh okay i see... i'll keep that in mind! :)

wait so oxidation happens at the anode in an electrolytic cell right? so would where oxidation happens be B??

and battery is E right? ;p

Answer 24

so G is positive terminal and therefore H is the negative?

Answer 25

What is oxidation @iheartfood ?

Answer 26

is that what it is then? :)

Answer 27

its the loss of electrons during a reaction right? :D

Answer 28

^^what oxidation is i meant haha :P

Answer 29

what do y'all think? :)

would that be correctly labeled above now? :) ^^^ :D

Answer 30

Well @iheartfood , can you tell me why you said that C is anode?

Answer 31

oh wait! you said cathode is bigger right? and in the diagram, C is bigger right?

so should it be the other way around? like this?

Answer 32

As per the hint given by me to you, cathode is larger than anode, in the figure, C is larger than F . So C is cathode.

Also, as the negative terminal is connected to C, so C is cathode . (not anode, sorry for not pointing out the mistake earlier , I was a little bit confused)

Answer 33

Good!

Answer 34

haha don't worry about it @mathslover :)

okay! yay!! so the above is all correct now right? :)

Answer 35

May be sometimes, you get difficulty knowing which is bigger , so use this hint :

If the negative terminal is connected to the electrode, then that electrode is cathode.

(Cathode has a negative charge)

Answer 36

but isn't C the cathode?

Answer 37

unless the oxidation actually occurs at D? :/ but wasn't D the conductor?

Answer 38

Sorry!

Answer 39

Oxidation occurs at F. (Anode)

Answer 40

its okay!! haha wait so are these correct then? :D
