Chapter 19, Problem 77A

Interpretation Introduction

Interpretation : The aqueous solution of salt is acidic, basic or neutral is to be predicted.

Concept Introduction : One of the products of a neutralization reaction is salt. Salt constitutes a cation from a base and an anion from an acid. They are neutral in solution form.

Answer to Problem 77A

The aqueous solution of salt is basic in nature.

Explanation of Solution

When salt is dissociated, its cations or anions either remove hydrogen ions or give hydrogen ions to water.

The given salt is ${\text{NaHCO}}_{\text{3}}$ .

The aqueous solution of ${\text{NaHCO}}_{\text{3}}$ is given below:

  ${\text{NaHCO}}_{\text{3}}\to {\text{Na}}^{+}+{\text{HCO}}_3^{-}$

The salt is formed by the aqueous solution of sodium chloride and ${\text{H}}_2{\text{CO}}_3$ ion.

It is the basic solution since it is formed between a strong base and weak acid.
