cell diagrams: anode and cathode? (1 Viewer)

[underthesun]

From multiple trustworthy sources (joel nothman note and this info page, it says that in cell diagrams, the left part will experience oxidation, while the right part will get reduction.

Is that true?

 

[Ragerunner]

its more common that the more active metal be placed on the left which is the anode and which oxidation occurs

as long as you label which is the anode and cathode i don't think it matters which way. its just left hand is more common

 

[underthesun]

ah ok

 

[Hottieflossy]

it might not always be like that...
oh, and here's a good mnemonic to use:
RED CAT meaning REDuction at the CAThode
AN OX meaning OXidation at the ANode

 

[Constip8edSkunk]

apparently the conventions are to put anode on the left and the cathode on the right but HSC doesnt adher to convensions...

 

[hipsta_jess]

not necessarilly...its just the anode is USUALLY drawn on the left, which experiences oxidation (highest on the table)...but in the hsc to trick ya and separate good from ordinary students they cood draw the cathode on the left (reduction)

Yep that's exactly right hipsta_jess I had a question exactly like that in my trials. The two metals were Pb(II) and Zn. So you go to your standard potentials sheet...see...which one is more reactive and bingo you have your anode and cathode. Quite simple really.

i never had a problem with this cos i never learnt it. just figured the active metal was oxidised, hence anodic.
