Answer:
Name and formula for the given acids are written below.
Explanation:
Add [tex]H^{+}[/tex] ions to each bases until it becomes neutral. This neutral form is the parent acid of the given conjugate bases.
a) [tex]HCO_{3}^{-}+H^{+}\rightarrow H_{2}CO_{3}[/tex]
[tex]H_{2}CO_{3}[/tex] ( carbonic acid)
b) [tex]H^{+}+IO_{4}^{-}\rightarrow HIO_{4}[/tex]
[tex]HIO_{4}[/tex] (periodic acid)
c)[tex]H^{+}+CN^{-}\rightarrow HCN[/tex]
HCN (hydrogen cyanide)
d) [tex]H^{+}+HS^{-}\rightarrow H_{2}S[/tex]
[tex]H_{2}S[/tex] (hydrogen sulphide)
