Chapter 10: Q.10.73 (page 358)

Complete the following table-

Short Answer

Expert verified

$H_{2} O$ conjugate base- $O H^{-}$

$C N^{-}$ acid- HCN

$H N O_{2}$ conjugate base- role="math" localid="1653111199726" $N {O_{2}}^{-}$

$H_{2} {PO}_{4}^{-}$ acid- $H_{3} P O_{4}$

Step by step solution

01

Given Information

A form acid-base pair consists of two substances that are exclusively different due to the presence of a proton (H⁺). A form acid is framed when a proton is added to a base, and a form base is shaped when a proton is eliminated from an acid.

02

Explanation

Acid $H_{2} O$ - when one $H^{+}$ is removed the conjugate base is formed which is $O H^{-}$

Conjugate base $C N^{-}$ - When one $H^{+}$ is added the acid is formed which is HCN.

Acid $H N O_{3}$ - when one $H^{+}$ is removed the conjugate base is formed which $N {O_{2}}^{-}$

Conjugate base $H_{2} {PO}_{4}^{-}$ - When one $H^{+}$ is added the acid is formed which is $H_{3} P O_{4}$
