If a person takes a small amount of chometz and is nullifies it into a large amount of matza [before Pesach], is he fulfilling the mitzva of biyur chometz?
That is a HUUUUGE "ding-a-rye" [Spanish for "World-War"] in the Acharonim. Rebbi Akiva Eiger believed that it is not because he didn't actually destroy the chometz as is necessary. He just changed its halachic status.
Howevah - many arugue. The Avnei Nezer [136/9] has a KNOCK-YOUR-SOCKS-OFF proof against him from a SEEMINGLY totally unrelated gemara in Menachos [48b]. See the gemara there from the bottom of 47b and you will understand better. The upshot is as follows. When one redeems a loaf of bread in the עזרה of the בית המקדש in order to remove its kedusha, it is considered as if he has brought a loaf of חולין bread into the עזרה. So we see, that even though he didn't actually bring the loaf of חולין into the עזרה, we still consider it as if he did because he brought the חולין into the עזרה [by redeeming it there from its kedusha].
So too, even though he didn't burn the actual loaf of bread, the fact that he transformed it into matza by means of bittul suffices to consider it as if he had burned the actual loaf.
The same principal applies in both cases - changing its halachic status is considered as if one changed the nature of the actual food.

SWEETEST FRIENDS!!!!
You don't have to drink on Purim in order to get drunk. All you have to do is learn Avnei Nezer...
