Chapter 13, Problem 13.20P

(a)

Interpretation Introduction

Interpretation:

Equivalence volume in milliliters has to be determined.

Concept Introduction:

EDTA or ethylenediaminetetraacetic acid is used for titration of majority of metals with help of formation of strong metal complexes in the ratio of $1:1$. It is utilized to bind metals, most commonly used in industrial processes. It is also used for prevention of food oxidation and in environmental chemistry.

Formula to calculate molarity of solution is as follows:

  $\text{Molarity of solution}\left(\text{M}\right)=\frac{\text{Moles of solute}}{\text{Volume }\left(\text{L}\right)\text{ of solution}}$        (1)

(b)

Interpretation Introduction

Interpretation:

Concentration of ${\text{M}}^{n+}$ at $V=\frac{1}{2}{V}_{\text{e}}$ has to be determined.

Concept Introduction:

(c)

Interpretation Introduction

Interpretation:

Fraction of free EDTA in form of ${\text{Y}}^{4-}$ at $\text{pH 9}\text{.00}$ has to be determined.

Concept Introduction:

(d)

Interpretation Introduction

Interpretation:

Value of conditional formation has to be determined.

Concept Introduction:

Conditional formation constant comes into play if effects of side chemical reactions are to be considered on assessment of ligand power to form complexes. It is denoted by $K_{\text{f}}^{\text{'}}$.

(e)

Interpretation Introduction

Interpretation:

Concentration of ${\text{M}}^{n+}$ at $V=V_{\text{e}}$ has to be determined.
