Chapter 15, Problem 86RQ

Interpretation Introduction

Interpretation:

The structures of ${\text{ Al(H}}_{\text{2}}{\text{O)}}_{\text{6}}{}^{3+}$ and the product formed after removal of protons based on VSEPR theory are to be given, and the favored structure of the deprotonated product is to be chosen.

Concept Introduction:

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

VSEPR is based on the arrangement of groups around a central atom in such a way that the groups suffer minimum repulsion.
