Hello,

I'm attempting to write up my lab report, and in this experiment we created our own AgCl electrode and used this to measure the voltage of several standards and an unknown.  A graph of the standards - Etest vs log[Cl-] - was produced as the calibration curve.

My question is, how do the values of E* and n relate to this calibration curve?  Is E* just the slope of the curve?  If so, then n is easy to calculate from there.  If not, I'm not sure what it is...

Thanks!

Take a look at Nernst equation. You need slope and intercept.
