### ln vs log

I've noticed that sometimes we use log instead of ln in the Nernst equation. I was wondering if there's a reason we would prefer to use log over ln or if there is no difference.

There is no difference in using log versus using ln. The main reason log is preferred is because it is used in measuring pH, so it is easier to keep the logarithm the same base across chemistry, rather than switching from ln to log.

They yield the same results though!

### Re: ln vs log

They are both just different ways to write the Nernst Equation, but they should yield the same answer

Using log makes it easier to find the pH because pH= - log [H+].

### Re: ln vs log

Using ln versus log will yield the same answer. The only reasons one might want to use log over ln is to stay consistent within chemistry (usually use log for concentrations) and pH is found by using log.

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
