What is the bond order of triiodide? 1 or 2?
 
 
1 hour later…
4:38 AM
what does this equation really look like? Fe^3+ + e- -> Fe^2+
because i believe both ions are bonded with water
 
5:18 AM
Hi DHMO, you still here?
 
@Biker yes
 
So I have a question about electrode voltage
Why not just measure the voltage of an electrode by taking the ionization energy and divide it by e charge of electron
I mean I have a hard time conceptualizing the voltage generated by an electrode
 
@Biker for example?
 
Like hydrogen, The ionization energy for it is 2.18 × 10 −18
 
@Biker that is the energy of H -> H+ + e- ?
 
5:22 AM
it gives out a voltage of 13.625 volts
Yes
Why cant we use this as a voltage for an electrode for example
 
How do you derive the energy of H2 -> 2H+ + 2e- from it?
You would need the energy of the H-H bond also
Try to factor that in and see if the results match
 
I haven't studied that yet it is in the third chapter of our book
after the electrochemical chemistry chapter
What is the result?
 
I haven't tried it
H–H: 436 kJ/mol or 4.52 eV
@Biker But, the electrode potential is relative
H2 -> 2H+ + 2e- is defined to be 0eV
 
So to break the bond and take the electrons away that requres 4.52 ev
?
@Dhmo
I know that it is relative
I just trying to conceptualize how the voltage is generated
 
@Biker well, as you said, energy per charge
 
5:28 AM
In wikipedia it says the absolute potential for hydrogen electrode is 4.44 +-0.2 volts
Which is close to the result
Absolute electrode potential, in electrochemistry, according to an IUPAC definition, is the electrode potential of a metal measured with respect to a universal reference system (without any additional metal–solution interface). == Definition == According to a more specific definition presented by Trasatti, the absolute electrode potential is the difference in electronic energy between a point inside the metal (Fermi level) of an electrode and a point outside the electrolyte in which the electrode is submerged (an electron at rest in vacuum). This potential is difficult to determine accurately....
 
@Biker how did you calculate that?
 
Calculate what? it is on wikipedia
 
@Biker I mean the 4.52 eV above
 
Well take the energy and divide it by the charge of electron
you get the voltage
 
How did you calculate the energy?
wait
the 4.52 eV was the energy of 2H -> H2, right
 
5:31 AM
Yes
well, voltage
 
but I thought you were trying to find the voltage of 2H+ + 2e- -> H2
@Biker eV is energy
 
Well isnt it the same? if you reverse
 
How are they the same?
 
It should conserve energy
 
but 2H -> 2H+ + 2e- takes energy
 
5:36 AM
Yes and the other reaction releases
 
but the energy of 2H -> H2 should not equal the energy of 2H+ + 2e- -> H2
 
:/
 
@Biker Wait, I might have a clue
@Biker because H+(g) is not H+(aq)
 
Ah
 
H2 -> 2H+(aq) (0eV)
this reaction is 0
 
5:39 AM
Well it is zero because we have set it to zero, isnt that right?
 
No, this is really zero
The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the compound from its constituent elements, with all substances in their standard states at 1 atmosphere (1 atm or 101.3 kPa). Its symbol is ΔHo f or ΔfHo. The superscript theta (zero) on this symbol indicates that the process has occurred under standard conditions at the specified temperature (usually 25 °C or 298.15 K). Standard states are as follows: For a gas: the standard state is a pressure of exactly 1 atm For a solute present in an ideal solution: a...
wait
then where are the electrons?
@Biker Should I take it to main?
 
Eehhh, I will study that chapter later then come back. might have a clue then
Main?
 
@Biker the main site
 
Yea please
 
Alright

Q: Discrepancy in Standard Hydrogen Electrode energy

@Biker
 
Thank you :D
I just would love to have a professional chemist and ask him all the questions that I have XD
 
6:52 AM
@Biker i am far from a professional chemist, you may consult @orthocresol or @Loong or @Wildcat (sorry for the pings)
 
7:08 AM
Why do Ag atoms form negative photograph
 
7:30 AM
@Biker what do you mean?
 
I mean in photography you have AgBr when Br gets hit by a photon/light it oxidizes and Ag gets reduced so you form Ag atoms
The resulting picture is negative which means The lighter the object is the darker it is in the picture
 
Terminology issue here........is it correct if I term a reaction intermediate's [Grignard reagent-Carbonyl group adduct] breakdown as 'decomposition' ? (I don't really see anything wrong with that, but just in case.......@DHMO , since you're picky with terms......any ideas, please? )
 
@AaronAbraham no idea
 
Darn.......
Trying to figure out how I need to frame my next question.....
But thanks anyway......
 
@Biker no idea as well
 
7:42 AM
@Biker You are correct. This is conventionally set to zero. Many people have done experiments to measure the "absolute" value, which is not 0.
 
Oh
So could you answer my confusion please @orthocresol?
 
8:05 AM
@Biker Sum of two ionisation energies for copper: Cu(s) -> Cu^2+(g) + 2e-
Standard reduction potential for copper: Cu(s) -> Cu^2+(aq) + 2e-
secondly, ionisation energies are (depending on your source) either changes in enthalpy or internal energy.
Whereas reduction potentials are obtained from Gibbs free energies: $\Delta G = -nFE$
 
Someone like the meta rant of the day?

@Rubisco WOOW!! This is monstrous!!
 
Meet the most downvoted post in the world
No really. Even Atwood didn't manage to get so many downvotes on a post.
 
8:23 AM
@orthocresol All right that is good, Now typically How do they electrode build a voltage across? My explanation would be that metals ionize until equilibrium leaving negative electrons on the electrode and positive ions in the solution thus creating a voltage across.
But what make the metals ionize? DHMO replied before that they get bond with water thus and the gibbs energy is negative so it is spontaneous. So the water used in cells is pure(Pure excludes the ions of electrodes and salt bridge)?
And how did they exactly measure the absolute potential of the hydrogen electrode
 
@Biker Don't know, gotta ask somebody else about the details of what goes on in the cell.
Don't know that either, it's in some research paper somewhere. Sorry.
 
Like I solved all the problems available to me about galvanic cells and electrolysis. But I just don't like to accept things until I fully get it
Like I am used to the fact that metal produce positive ions
If I try to explain it, nope. However, I probably agree with DHMO's answer because it must be

Q: What is the non-ideal equivalent of mass action kinetics?

NathanielStarting from the equations of mass action kinetics, one may show that (for suitably chosen numbers $A_i$), the function $\sum_i x_i(A_i + \log x_i)$ is a Lyapunov function, i.e. it decreases over time. Apart from an irrelevant factor of $RT$, this is the expression for the free energy of an ide...

Q: What element when mixed with water can produce great odor and kill bad odor?

@Loong That's THE comment!
 
1:29 PM
I've had conversations in real life that included that comment...
 
@orthocresol I told him use valeric and butyric acids
 
@9-BBN doesn't work; it has to be an element :)
I think a healthy dose of caesium would do the trick, but then it might kill more than the bad odour ^^
 
I work at Givaudan during my internship in a fragance application laboratory I know some bad smells now :P
 
looks up valeric acid
 
He said an "ingredient"
Is that the same as an element?
 
1:32 PM
@9-BBN The title has element. Of course, I have no clue what he is looking for.
 
Oh he might non be english "element" in French can refeer as more than "element" of the table
 
I think that is clear enough from the profile. :)

@Rubisco That might have something to do with a certain flag.
 
@Mart it's funny how Proforma adds a "Welcome to Chemistry!" to the beginning of every new-user-targeted comment. What if someone takes it literally?

The constants should be upright, no?
 
user116211
Which one?
 
user116211
I use \mathcal to distinguish constants from other letters.
 
@MAFIA36790 R
The ideal gas constant
 
user116211
$$P V = N\mathcal R T$$
 
4:24 PM
\mathcal? Not sure.
It's not for decoration. Special constants get the mathcal.
 
user116211
\mathfrak for decoration ;P
 
@Rubisco I'm not sure, some people like to use \mathcal{R} but I just stick to plain old R.
 
user116211
I've seen many literatures using \mathcal to write constants.
 
Also, I usually use small p for pressure and not big P.
 
4:27 PM
@orthocresol But I thought that's for special constants.
 
user116211
However, \mathcal is generally used for writing operators.
 
Like using mathbb for real numbers.
 
I don't know. The only time I've actually used mathcal was for Laplace transform.
 
user116211
@Rubisco \mathbb is used for any algebraic structure.
