Does anyone know the equation of what happens at the cathode ??

Thanks

 

[Dreamerish*~]

NH₄⁺ + MnO₂ + H₂O + e^- → Mn(OH)₃ + NH₃

You can still get away with full marks if you don't include these equations. They're rather long and confusing.

Yeah
Try and learn the cell structure though

Zn |ZnCl₂, NH₄Cl|MnO₂, C

oh thats much easier to remember.

do u know the structure for fuel cell?

does mentioning this structure enough with out writing out full cathode and anode equations to compare?

 

[richz]

its hydrogen and oxygen its on the data sheet

 

[MuffinMan]

how can u get away with full marks without the equations? i have no idea how to remember them :-/

i can't find out what it use for salt bridge. but it does use an catalyst.

H2O2llH2O

is it like that?111
