I don't know why, but I just can't figure this out.(adsbygoogle = window.adsbygoogle || []).push({});

"Calculate the electrode potential for a silver filled electrode in a solution of 0.00550 M AgNO3 solution."

I got that

Ag+ + e- --> Ag(s) had an E* = .80V

I got that the answer is E=.80 - .0592 log (1/.00550M)= .6655 V

But why do you put 1/.00550M in the parenthesis?

My first thought was that AgNO3 + e- --> Ag(s) + NO3-

and that the concentreation of AgNO3 is the same as NO3.

so that it would be log(1) , which is wrong.

I just don't get the concept I guess.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
