Give the conjugate acid of the following bases: a) NH2-, b) CO3 ^2-, c) HS-, d) OH-

H+ + Base = conjugate acid of Base

therefore,
(a) NH3
(b) HCO3^-
(c) H2S
(d) H2O

so there,, =)

ok, i got them. just want to make sure the answer are correct. thanks

a) The conjugate acid of NH2- is NH3.

b) The conjugate acid of CO3^2- is HCO3-.

c) The conjugate acid of HS- is H2S.

d) The conjugate acid of OH- is H2O.

To determine the conjugate acid of a base, you need to add a hydrogen ion (H+) to the base molecule. Here are the conjugate acids of the given bases:

a) NH2- (ammonia): To obtain its conjugate acid, you need to add an H+ ion to ammonia. The resulting molecule is NH3, which is the conjugate acid of NH2-.

b) CO3^2- (carbonate): Adding an H+ ion to carbonate gives you HCO3-, which is the conjugate acid of CO3^2-.

c) HS- (hydrogen sulfide): Adding an H+ ion to hydrogen sulfide results in H2S, which is the conjugate acid of HS-.

d) OH- (hydroxide): The conjugate acid of hydroxide is water (H2O). When an H+ ion is added to OH-, it forms H2O, which is the conjugate acid.

To summarize:

a) NH2- (base) -> NH3 (conjugate acid)
b) CO3^2- (base) -> HCO3- (conjugate acid)
c) HS- (base) -> H2S (conjugate acid)
d) OH- (base) -> H2O (conjugate acid)
