Q.10.73 - An Introduction to General, Organic, and Biological Chemistry

Question

Complete the following table-

Step-by-Step Solution

Answer

$H_{2}O$ conjugate base- $O{H}^{-}$

$C{N}^{-}$acid- HCN

$HN{O}_2$ conjugate base- $N{O_2}^{-}$

${\mathrm{H}}_2{\mathrm{PO}}_4^{-}$acid- $H_{3}P{O}_4$

Step 1: 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.

Step 2: 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$HN{O}_3$- when one $H^{+}$ is removed the conjugate base is formed which $N{O_2}^{-}$

Conjugate base ${\mathrm{H}}_2{\mathrm{PO}}_4^{-}$- When one $H^{+}$ is added the acid is formed which is $H_{3}P{O}_4$
