Chapter 20, Problem 83AE

Interpretation Introduction

Interpretation:

Ionic or covalent character of sodium hydride and the given reaction is Oxidation-reduction reaction and acid-base reactionshould be explained.

Concept introduction:

A molecule is neutral group of two or more atoms joined together by chemical bonds.

Ionic compound is a composed of ions held together by electrostatic forces called as ionic bond. The compound is neutral, it is of consists positively charged ions called cations and negatively charged ions called anions.

Compounds of metals with nonmetals are usually called as ionic, nonmetal-nonmetal compounds are usually molecular.

The ion or molecule that accepts electrons is called the oxidizing agent and the species that donates electrons is called the reducing agent.

According to acid base theory, an acid gives the hydrogen (proton) ion and a base is accepting the hydrogen (proton).
