Determination of Single Electrode Potential
. fig 5.13 Example: electrode a cell made of a Zn electrode immersed in 1M ZnSO 4 is coupled with a S.H.E. The E.M.F. of the above cell is 0.76V. The direction of flow indicates that oxidation takes place so a standard reduction potential of -0.76V is given to i..

Measurement of Electrode Potential
Measurement of Electrode Potential - The absolute value of single electrode potential cannot be determined because the oxidation half reaction cannot take place without the reduction half. To overcome this difficulty the standard hydrogen electrode (SHE) is taken as the standard..

very helpful of a complex problem, oh my god I would have never completed this problem with out the tutor. Tutor vista thank u so much.
This is my favorite tutoring ever. i might say that to others to, but this tutoring has thought me the most from any tutorings!! -Ashlyn
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
