Chapter 2, Problem 2.13P

Interpretation Introduction

Interpretation:

Three glass bottles were crushed and sieved to collect $\text{1-mm}$ pieces to see how much $\text{Al}$ could be extracted, $\text{200 mL}$ of $\text{0}\text{.05 M}$ solution of the metal-binding compound EDTA were stirred with $\text{0}\text{.05 g}$ of $\text{1-mm}$ glass particles in a polyethylene flask.  The $\text{Al}$ content of the solution after two months was $\text{5}\text{.2 μM}$. The total content of the glass, measured after completely dissolving some glass in $\text{48 wt\%}$ hydrogen fluoride with microwave heating, was $\text{0}\text{.80 wt\%}$.  The fraction of $\text{Al}$ extracted has to be calculated.
