Chapter 15, Problem 71RQ

Interpretation Introduction

Interpretation:

The reason due to which compound ${\text{Mg(OH)}}_2$ is basic in nature, but ${\text{Si(OH)}}_4$ is an acid to be discussed.

Concept Introduction:

Bronsted-Lowry acids is the species that donates ${\text{H}}^{+}$, and those which accept ${\text{H}}^{+}$ are considered as Bronsted-Lowry bases. The species formed when a Bronsted-Lowry acid donates ${\text{H}}^{+}$ is called its conjugate base, while that formed when a Bronsted-Lowry base accepts ${\text{H}}^{+}$ is called its conjugate acid.

Ionic compounds like hydroxides of alkali metals are basic in nature, as these release hydroxide ions in solution. Covalent hydroxides such as those of p-block elements release protons and behave as acids.
