Chapter 15, Problem 35RQ

Interpretation Introduction

Interpretation:

The element whose oxide forms an acidic solution is to be classified as a metal or a non-metal.

Concept Introduction:

Bronsted-Lowry acids are those species which donate ${\text{H}}^{+}$ and those which accept ${\text{H}}^{+}$ are considered as Bronsted-Lowry bases. The species formed after the donation of ${\text{H}}^{+}$ by a Bronsted-Lowry acid is called its conjugate base while that formed after accepting ${\text{H}}^{+}$ by a base is called its conjugate acid.

Metals are characterized by their luster, high thermal and electrical conductivity, sonorous nature, ductility, malleability, the formation of ionic hydroxides and tendency to release hydroxides in solution.

Non-metals are characterized by their rough surface, low melting and boiling point, low or no thermal and electrical conductivity, the formation of covalent oxides and tendency to release protons in solution.
