Chapter 1, Problem 66P

Interpretation Introduction

Interpretation:

For each of the acid-base reaction, the acid, base, conjugate acid, and conjugate base are to be identified. The equilibrium constant for each of reaction is to be calculated.

Concept introduction:

An acid is a chemical substance that readily donates protons and a base is a chemical substance that can easily accept a proton. During an acid-base reaction, the interaction between an acid and a base is taken place because of the transfer of a proton.

The equilibrium constant expression for an acid-base reaction is written as follows:

$K_{\text{eq}}=\frac{{\text{10}}^{\text{-}p{K}_{\text{a(react)}}}}{{\text{10}}^{\text{-}p{K}_{\text{a(prod)}}}}$

Here $K_{\text{eq}}$ is the equilibrium constant, $p{K}_{\text{a(React)}}$ is the acidic strength of reactant acid and $p{K}_{\text{a(prod)}}$ is the acidic strength of acid formed during the reaction.
