how come sulfate arent basic, why dont they form bi sulfate like carbonates form bicarbonate?

In fact they do, but just a little bit. Sulfate ion is a little bit basic. The reason that it is only a little bit is that HSO4(-) is a fairly strong acid.

 

Take a concentrated solution of e.g. sodium sulfate and you'll see that it is very weakly basic:

 

SO4(2-) + H2O <<<---> HSO4(-) + OH(-)

Just wondering, aren't sulfates a Brohnsted base? They are proton acceptors...

Yes, sulfates can and do act as Bronstead bases.

sulfates are bronsted bases, altho theyre absolutely dreadful bases, hence the high acidity of H2SO4
