Give the formula for the conjugate base of each acid.
a. HSO4-
H2SO4-
b. H3PO4
H4PO4
c. HPO42-
H2PO42-
d. HNO3
H2NO3
a. SO4^2-
b. H2PO4
c. PO4^2-
d. NO3^-
nope. All need reworking.
HSO4^- + H2O ==>H3O^+ + SO4^2-
SO4^2- is the conjugate base of HSO4^-
a. The conjugate base of HSO4- is SO42- (sulfate ion).
b. The conjugate base of H3PO4 is H2PO4- (dihydrogen phosphate ion).
c. The conjugate base of HPO42- is H2PO42- (monohydrogen phosphate ion).
d. The conjugate base of HNO3 is NO3- (nitrate ion).
To find the formula for the conjugate base of each acid, you need to understand the concept of acid-base reactions and the concept of conjugate acids and bases.
In an acid-base reaction, when an acid donates a proton (H+) to another substance, it forms its conjugate base. The conjugate base is the compound that remains after the acid loses a proton.
Now let's find the conjugate base for each acid:
a. HSO4-
The acid here is H2SO4 (sulfuric acid). To find its conjugate base, you need to remove one proton (H+) from the acid. So, the formula for the conjugate base is SO42-.
b. H3PO4
The acid here is H3PO4 (phosphoric acid). To find its conjugate base, remove one proton (H+) from the acid. So, the formula for the conjugate base is H2PO4-.
c. HPO42-
The acid here is H2PO42- (dihydrogen phosphate ion). To find its conjugate base, remove one proton (H+) from the acid. So, the formula for the conjugate base is HPO42-.
d. HNO3
The acid here is HNO3 (nitric acid). To find its conjugate base, remove one proton (H+) from the acid. So, the formula for the conjugate base is NO3-.
To summarize:
a. Conjugate base of HSO4- is SO42-
b. Conjugate base of H3PO4 is H2PO4-
c. Conjugate base of HPO42- is PO43-
d. Conjugate base of HNO3 is NO3-
