"It is impossible to ascertain" vs "It is impossible to ascertain who"

Both phrases are correct, but they are used in different contexts. The phrase 'it is impossible to ascertain who' is used when you want to specify the subject being ascertained, while 'it is impossible to ascertain' is more general and does not specify the subject. Therefore, the choice between the two depends on whether you want to include the subject being ascertained or not.
