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? :)
how do you say cathode is D?
Well, i dont think that cathode is D. Was it given initially that D is cathode or is it just according to you @iheartfood ?
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 :/
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 :(
Cathode is the metal "in the solution".... , is D present in the beaker or solution?
Check this it should help http://en.wikipedia.org/wiki/Electroplating
oh.. no it isn't! so it has to be either F or C right? :)
Yep , good.
Well, can you say me, what is D now?
okay.. so based off that link, is F the cathode? And C is the anode?
yes, i heart
i'm not sure what D is haha :(
ooh! yay! :)
D is a conducting wire ... (or just a conductor ? :) )
so we have this so far now! :)|dw:1370147720251:dw|
ohh okay i see... so i don't label D right? Cuz conductor isn't one of the things I'm labeling?
A could be flow of electrons|dw:1370147780457:dw|
A trick for you to recognize anode and cathode : Cathode is much larger than anode.
electrons goes into the positive terminal of the battery
@iheartfood battery should be easy to idenitfy
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
so G is positive terminal and therefore H is the negative?
What is oxidation @iheartfood ?
|dw:1370147897825:dw| is that what it is then? :)
its the loss of electrons during a reaction right? :D
^^what oxidation is i meant haha :P
what do y'all think? :) would that be correctly labeled above now? :) ^^^ :D
Well @iheartfood , can you tell me why you said that C is anode?
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? |dw:1370148222624:dw|
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)
haha don't worry about it @mathslover :) okay! yay!! so the above is all correct now right? :)
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)
but isn't C the cathode?
unless the oxidation actually occurs at D? :/ but wasn't D the conductor?
Oxidation occurs at F. (Anode)
its okay!! haha wait so are these correct then? :D|dw:1370148548968:dw|
oh it does? does it always occur at the anode?
Reduction always occur at Cathode and oxidation always occur at Anode.
ohh oaky :) |dw:1370148687342:dw| so this is the final correct answers? :D
Looks sweet to me :P , yes I think so.
okay, awesome!! :) Thank you so much @mathslover :)
:) You're welcome @iheartfood
