This is also from the lab concerning activity serious of metals and calculation of electrode portentions...

Question:
What are the standard conditions for measuring potentials?

Does that mean...
Standard condition for temp: 298K
Concentration: 1 molar concentration
Pressure: 1 atm

Am I interpreting this right, and/or am I missing something?

Thanks

All of my references are dated. Internet references don't have dates as to when they were written or the origin of the data. All, however, seem to agree on 25o C as the standard temperature. Most references say 1 molar as the standard concentration but a few note an "activity" of 1. IUPAC recommeded a standard pressure of 1 bar and not 1 atmosphere (a small change), perhaps as early as 20 years ago; however, in chemistry texts copyrighted as recently as 2000, 1 atm is noted as the standard pressure. I am sorry to see chemistry falling into this sprial of uncertainty where books, references, recommendations, even standard conventions, blur what is real, what is thought to be better, what is in the process of being negotiated, etc. In one word, it stinks.
