It actually doesn't matter whether you use the log version or the ln version; the log version is an altered version of the ln version, so both should give the same result.

It does not matter. But using log is more convenient when calculating for pH.

Both versions give you the right answer. However, on the equation sheet, the log version is a constant over n, so you have to keep in mind that the constant given can only be used if the reaction is taking place at 25 Celsius.
