Chapter 12, Problem 12.91QP

Interpretation Introduction

Interpretation: The formula of kaolinite, obtained by the replacement of ${\text{Al}}^{3+}$ in $\left[{\text{Al}}_2\left({\text{Si}}_2{\text{O}}_5\right){\left(\text{OH}\right)}_{\text{4}}\right]$ with ${\text{Mg}}^{\text{2+}}$ ions is to be stated.

Concept introduction: A single replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products.

To determine: The formula of kaolinite, obtained by the replacement of ${\text{Al}}^{3+}$ in $\left[{\text{Al}}_2\left({\text{Si}}_2{\text{O}}_5\right){\left(\text{OH}\right)}_{\text{4}}\right]$ with ${\text{Mg}}^{\text{2+}}$ ions.
