Re: Nernst
If you are using the shortcut E=E(naught)-(0.05916/n)logQ, you need to use log. I think there is another number shortcut if you are using the equation with natural log.

Is this the equation given on the equation sheet?
Re: Nernst
I don't think I saw the shortcut equation with .05916 on the equations sheet so I used Ln

Re: Nernst
You usually use ln, just because it is more direct and it is also given to us on our equation sheets. If you want to use log however, just multiply by the conversion factor, it shouldn't really matter in the end

Re: Nernst
You can use either but if you are trying to find the pH as in some of the HW problems, it would be easier to use the log version so you can find -log{H3O+].

Re: Nernst
You can use either, the equation sheet lists both so whichever you are most comfortable using is best.

Re: Nernst
When a problem is asking for you to solve for the pH or when you are given pH in a cell diagram, that's when you would usually use log instead of ln. Hope this helps!
