akcapr Posted September 27, 2005 Posted September 27, 2005 how come sulfate arent basic, why dont they form bi sulfate like carbonates form bicarbonate?
woelen Posted September 27, 2005 Posted September 27, 2005 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(-)
rthmjohn Posted September 27, 2005 Posted September 27, 2005 Just wondering, aren't sulfates a Brohnsted base? They are proton acceptors...
Yggdrasil Posted September 27, 2005 Posted September 27, 2005 Yes, sulfates can and do act as Bronstead bases.
budullewraagh Posted September 27, 2005 Posted September 27, 2005 sulfates are bronsted bases, altho theyre absolutely dreadful bases, hence the high acidity of H2SO4
