Answer
a. $ HSO{_4}^{-}$
b. $ HCN$
c. $NH{_4}^+$
d. $HCl{O_2}$
e. $H_2S$
Work Step by Step
- To find the conjugate acid of a base, just add a $H^+$ to its chemical formula.
1. Add a hydrogen:
a. $SO{_4}^{2-} \longrightarrow HSO{_4}^{2-}$
b. $CN^- \longrightarrow HCN^-$
c. $NH_3 \longrightarrow NH_4$
d. $Cl{O_2}^- \longrightarrow HCl{O_2}^-$
e. $HS^- \longrightarrow H_2S^-$
2. Add 1 to their charges.
a. $HSO{_4}^{2-} \longrightarrow HSO{_4}^{-}$
b. $HCN^- \longrightarrow HCN$
c. $NH_4 \longrightarrow NH{_4}^+$
d. $HCl{O_2}^- \longrightarrow HCl{O_2}$
e. $H_2S^- \longrightarrow H_2S$
