Which video is supposed to be Senior Chemistry: Redox 2?

[bannanaiscool]

@tubeuser147 Gotta go to the website!

why don't you multiply the Ag E(not) value by 2?

[bannanaiscool]

The standard voltages are not dependent on the number of moles of electrons exchanged. You never multiply any half rxn voltage to get a net voltage.

[zapcannon99]

I only have one problem, the net reaction's product has a coefficient for the Silver

2Ag+ + Pb -> Pb+2 + 2Ag

[bannanaiscool]

Thanks and bravo for noticing that! I did forget to put the 2 in front of the silver metal.

positive enot= spontaneous

negative enot= nonspontaneous right?

[LUisRIcaRDoOJ]

i can tell from this videos that you really love chemestry....XD you handle it very well

LEO says GER

Loser Electrons - Oxidation

Gain Electrons - Reduction

[thaitanium2005]

2:53 its even better

you reverse the sign!!!

[BabysFace]

Listen to how he says r, on the right side gets reversed at 1:30. Its hilarious

OIL RIG

Oxidation Is Loss (of electrons)

Reduction Is Gain (of electrons)

[jesse20100]

our professor taught us some acronym for red-ox:

O.R.A.L.I.= Oxidation Reducing Agent Loss (of electron) increase

R.O.A.G.D.= Reduction Oxidizing Agent Gain(of electron) Decrease

[malubayraymond]

yes, AK27 is right. Our mentors revised the original equation to a more simple one. (Ecell-E(reduc)-E(oxi). in that way, students dont have to bother reversing the reduction potentials.

[satanspsychic]

why isn't the Ag on the right a 2Ag.. but the Ag on the left becomes 2Ag

[zxAK27xz]

It is but he reversed it to make it positive so instead of doing .80 - - .13 he did .80+.13
