Chapter 7, Problem 29A

Interpretation Introduction

Interpretation :

An unbalanced chemical equation must be written for the preparation of silver nitrate along with hydrogen gas by dissolving metallic silver in concentrated nitric acid.

Concept Introduction :

An unbalanced chemical equation is the representation of a chemical reaction in which each atom are not made equal in both the sides of the equation.

Silver is oxidized to silver nitrate when it is reacted with nitric acid which is reduced to hydrogen gas.

Answer to Problem 29A

An unbalanced equation for the preparation of silver nitrate along with hydrogen gas by dissolving metallic silver in concentrated nitric acid is given below.

  ${\text{Ag(s)+HNO}}_{\text{3}}\text{(aq)}\to {\text{AgNO}}_{\text{3}}{\text{(aq)+H}}_{\text{2}}\text{(g)}\text{.}$

Explanation of Solution

From the reaction it can be seen that silver is converted to silver nitrate and hydrogen gas is produced. It is an oxidation-reduction reaction in which nitric acid is an oxidant and silver is a reductant. All the physical states of reactants and products are given in bracket.
