Chapter 22, Problem 22.90AP

Interpretation Introduction

Interpretation: The concentration ratio of the free (and potentially toxic) ${\text{Pb}}^{2+}\left(aq\right)$ in the blood to the much toxic $\text{Pb}{\left(\text{EDTA}\right)}^{2-}$ for the given values is to be calculated.

Concept introduction: The formation constant for formation of a complex is calculated by the formula,

$K_{\text{f}}=\frac{{\left[\text{Product}\right]}^y}{{\left[\text{Reactant}\right]}^x}$

To determine: The concentration ratio of the free (and potentially toxic) ${\text{Pb}}^{2+}\left(aq\right)$ in the blood to the much toxic $\text{Pb}{\left(\text{EDTA}\right)}^{2-}$ for the given values.
