Is H2SO4 amphiprotic?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

It is

OpenStudy (waheguru):

because i was confused wether Na2So4 was a acidic or basic. It should be neutral but a pH test said it was baic

OpenStudy (waheguru):

Na2SO4 occurs when NaOH and H2SO4 react. both are strong bases and acids producing weak conjugate acids and bases so shouldnt it have been neutral?

OpenStudy (waheguru):

but the ph test indicated it had a ph of 9 :S

OpenStudy (waheguru):

any idea?

OpenStudy (waheguru):

let me rephrase my question. there is a salt Na2SO4. will its solution be acidic neutral or basic?

OpenStudy (waheguru):

? anyone here ?

OpenStudy (anonymous):

Neutral

OpenStudy (nottim):

Neutral? I dunno

OpenStudy (nottim):

Even if its a weak anything, neutral requires it to be exactly 7. I think the LEO GER or OIL RIG (oxidiation/reduction) principles may help.

OpenStudy (nottim):

Also, pH applies to solids too right?

OpenStudy (anonymous):

Na2SO4, or sodium sulfate, is a salt formed in a neutralization reaction with sulfuric acid (an acid) and sodium hydroxide (a base). So it is neither an acid or base, it is a salt.

OpenStudy (ookawaiioo):

YES! its amphoteric!

OpenStudy (nottim):

should explain that. im confused.

OpenStudy (anonymous):

Which one? and thx for the medal
