Chapter 9, Problem 74A

Interpretation Introduction

Interpretation: It is to be explained whether all compounds containing hydrogen are acids.

Concept Introduction: Species that can donate ${\text{H}}^{\text{+}}$ ions in an aqueous solution are said to be acidic in nature. They react with the base to form corresponding salt and water. This type of reaction is called a neutralization reaction.

Answer to Problem 74A

Not every compound that contains hydrogen atoms is acid.

Explanation of Solution

Species that can donate ${\text{H}}^{\text{+}}$ ions are called acids, e.g: HCl, ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}},{\text{HNO}}_{\text{3}}$ , etc. But compounds ${\text{CH}}_{\text{4}}\text{,}\text{NaOH,}\text{NaH,}\text{etc}\text{.}$ containing hydrogen atoms are not acids.
