Could Jesus save Satan?
Some biblical reference with explanation, would be helpful.

There is very little in Scripture directly about Satan, so biblical references aren't really going to exist.
One thing to clarify, however, is the meaning of Satan as opposed to Beelezub, Lucifer, or the Devil. It should be noted that while we all think this is the same bad guy, the primary reference to Satan (and really the only one from which much can be gleaned) is in the first two chapters of Job.*
Ha-Satan literally means "the Accuser." To "save" a (false) accuser, presumably from the results of his lying would mean forcing him to withdraw his charge. Once "the Accuser" is no longer Accusing, what is he? He can be defeated (and will be!), or silenced, but to be "saved" would be to deny the very essence of what he is.
Thus, the answer is "No."
Its not because God doesn't have the power, or even the desire - its because of the law of non-contradiction.
*For completeness' sake, here are all the references, via Wikipedia:
The Bible reveals no provision of salvation for angelic beings, while it speaks quite a bit about the provision of salvation for mankind. It also speaks of "the eternal fire" as a place prepared for the devil and his angels...
Theologically speaking, there is no "first Adam" of the race of angels, because they neither marry nor are given in marriage.
So, without a "first Adam", there could be no "Second Adam", and consequently, no Savior.
