Chapter 10: Q.10.104 (page 360)

Identify the conjugate acid-base pairs in each of the following equations:
a. ${HNO}_{2} (a q) + {HS}^{-} (a q) ⇄ {NO}_{2}^{-} (a q) + H_{2} S (g)$
b. $HCl (a q) + {OH}^{-} (a q) ⟶ {Cl}^{-} (a q) + H_{2} O (l)$

Short Answer

Expert verified

Part (a) . ${HS}^{-} (a q) \to H_{2} S (a q)$ and $HCl (a q) \to {Cl}^{-} (a q)$

Part (b) . $H_{2} O (l) \to {OH}^{-} (a q)$ and ${HNO}_{2} (a q) \to {NO}_{2}^{-} (a q)$

Step by step solution

Given Information (Part a)

In the Brønsted-Lowry meaning of acids and bases, a conjugate acid-base pair comprises two substances that vary exclusively by the presence of a proton. A conjugate acid is framed when a proton is added to a base, and a conjugate base is shaped when a proton is eliminated from an acid.

Explanation Part (a)

A conjugate acid is framed when a proton is added to a base, and a conjugate base is shaped when a proton is eliminated from an acid.

Hence,

the conjugate acid-base pairs are,

${HS}^{-} (a q) \to H_{2} S (a q)$ and $HCl (a q) \to {Cl}^{-} (a q)$

Explanation Part (b)

A conjugate acid is framed when a proton is added to a base, and a conjugate base is shaped when a proton is eliminated from an acid.

Hence,

the conjugate acid-base pairs are,

$H_{2} O (l) \to {OH}^{-} (a q)$ and ${HNO}_{2} (a q) \to {NO}_{2}^{-} (a q)$
