WebbAmmonia will be protonated by acetic acid (pKa 4.76), but deprotonated by an alkane with a negative charge/lone pair (pKa 50). In this case ammonia can be acidic or basic, making it amphoteric (can act as an acid or a base). However, it can never have both a positive and negative charge at the same time, so ammonia cannot be zwitterionic.
