Galvanic. stav is fucked

[onlyfknhuman]

question 6 short answer,

it asks the direction of the electron. which is from anode to cathode, hence zinc to copper it says.

then it askes u to write the equations of teh anode and cathode

the anode was zn -> zn2+ +2e-
and the cathode was 2H++2E- -> H2

the question states, that it produces hydrogen at the cathode.

But why does the answwer to the previous question say that its going from zinc to copper.

-_-'so shuldnt the cathode be a copper half equation

[roly182]

Copper can still act as a cathode but just not react.. it is just a conductive metal used as an electrode as the surface for the reduction of hydrogen ions

[ed_saifa]

Zn is a stronger reductant than Cu and so will be preferentially oxidised.

[onlyfknhuman]

oh fuck is copper an inert electrode... totally blanked out on that

[Mao]

no, copper is not inert

but Zn is a stronger reductant, and H+ is the strongest oxidant, hence copper in this case doesn't react.
