Homework Help: chem

Posted by Erik on Sunday, January 29, 2012 at 10:47pm.

Ok so for question I have to state whether the element/compound is an acid, base, conjugate acid or conjugate base. Can u please tell me if i am correct and help me out with the ones i am unsure what the answer is?

1)S^2-(aq)+HCl(aq)<=>Cl^1-(aq)+HS^1-(aq)
This is what I think the answer is:
Acid = HCl
Base = S^2-
Conjugate acid =Cl^1
Conjugate base = HS^1-


2)H2O2(aq)+PO4^3-(aq)<=>HPO4^2-(aq)+ HO2^1-(aq)
This is what I think it is:
Acid = H2O2
Base = PO4^3-
Conjugate acid =unsure
Conjugate base = unsure


3)IO3^1-(aq)+HI(aq)<=>I^1-(aq)+HIO3(aq)
This is what I think it is:
Acid = HI
Base = IO3
Conjugate acid =HIO3
Conjugate base = I^1-

4)H2SO4(aq)+CN^1-(aq)<=>HSO4^1-(aq)+ HCN(aq)
This is what I think it is:
Acid = H2SO4
Base = CN^1-
Conjugate acid =unsure
Conjugate base = unsure
