Finding n

Postby Haley Dveirin 1E » Sat Feb 22, 2020 6:41 pm

How do you find n? does it have to do with moles like the variable n has in the past or is it the number of electrons being transferred?

"n" in electrochemistry refers to the number of moles of electrons transferred. It is usually found using the same methods as before: using the given values to isolate n in the required equation.

Hi- n does refer to moles in electrochem, just like before. An example of this is the delta G standard=-nFEcell equation. N can usually be found in electrochem questions just by looking at the redox reaction or balancing the given equation.

Considering the constant F in electrochemistry, it can be concluded that n refers to the number of moles of electrons being transferred and this is easy to remember since redox reactions come down to an exchange of electrons reducing or oxidizing an atom or molecule.

"n" means moles of electrons and can easily be found by looking at your balanced redox reaction and looking at the number of electrons that were transferred.

So this is the number of moles of electrons transferred after the entire redox reaction and not the total of electrons transferred in each part of the balanced equation?

For electrochemistry in this case, you can identify the n (as moles/electron in this case) from balancing your redox reaction since redox reactions involve the transfer of electrons.
