Quick Chem question...
Say I have a Zinc anode in a galvanic cell, and the zinc is oxidized, and it becomes a cation.... WHAT is its Anion?

>> No.2900013

No Chem-anons on?

>> No.2900034

I always called anions "an-yuns"

and cations "cash-uns"

>> No.2900068

What do you mean its anion?

>> No.2900081

the one that migrates into that compartment from the salt bridge connecting the cell.

>> No.2900094

>>2900034
actually "anion" is pronounced "Uhn-yun"
whenever you generate anions via reduction of an elemental material (single electron transfer for example), you generate an anion that catalyzes the formation of gasses that make you tear up.


the great thing about anions is that, when mixed with the proper biologically relevant chemicals, you can generate flavor causing and aromatic compounds that are ubiquitous in modern kitchens.


anions are extremely important in food chemistry.

>> No.2900115

it depends on the electrolyte solution the electrode is in, but its probably hydroxide or oxide.

Zinc sulfate solution.
>>2900068
Zinc is oxidized into a Cation, and therefor it creates a salt...BUT all I see is Zn<span class="math">^{2+}[/spoiler] where's the -2 Anion?

>> No.2900229

>>2900198
sulfate is the anion. its SO4(-2)

>> No.2900234

Sulfate, most likely.
But it doesn't matter anyways; the redox reaction does not involve the spectator anion.

I can't see it oxidizing into zinc sulfate, I mean, where is the extra sulfate ions coming from?

Uhhn-
UUUUHHHHHHHHHHN
OOOONNION.
There we go.

>> No.2900260

What? In a zinc sulfate solution the zinc already exists as the cation Zn2+. If you apply a current then Zn2+ will be reduced to zinc metal at the cathode

>> No.2900261

>>2900240

zinc ions get reduced to zinc metal at the anode.

Okay, If you're oxidizing zinc metal into a solution, of zinc sulfate,...That means that ever zinc in the sulfate solution ALREADY has a co-exsisting ion...

So, If you oxidize zinc, It could not possibly make more zinc sulfate....What does it make?
