I just started with electrochemistry.

I know that when the standard electrode potential is positive it means the reaction is spontaneous.

However, I have no idea how to calculate the standard electrode potentials for the reactions given in following question. Like, which values do I look up on the activity series and what do I add subtract etc..

The answer is E) btw...

Consider writing any reactions that you think may take place, then use the table to calculate E⁰ values for these.

Does it? Titanium and tantalum are used for their excellent resistance to corrosion.

And..? This may be confusion of the definition of spontaneous in this case..?

@OP,

Have you studied both half-cell and full-cell potentials?

thts the thing idk what equations to use dude...

idk wht on earth is being oxidised and whats being reduced. especially with the oxygen and iron sulfates. i get the zinc and copper stuff cuz thats easy, but what equations do i use for the iron sulfate?

It was. Thanks!

Can you calculate the oxidation number of iron in FeSO₄?
