pKa 2.8 acidic => negatively charged at pH 7 (e.g. acetic acid)
pKa 2.8 basic => neutral at pH 7 (e.g. cyclophosphamide or 3-nitroaniline)

pKa 2.8 => can be anything

I have never heard about such use of acidic/basic adjective. Can you show us a reference?

What about hydrocyanic acid? pKa 9.31. Basic?

What about hypothetic pKa=7.00 acid, 50/50 at pH=7.0? Basic? Acidic? Neutral?
