Conditional formation constant for Mg ( EDTA ) 2 − at pH 9 .00 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 f ' .

Question

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. དྲ。 ✗MgBr ? O CI Will the first product that forms in this reaction create a new C-C bond? Yes No • ? Will the first product that forms in this reaction create a new CC bond? Yes No × : ☐ X

Question

Chapter 13, Problem 13.19P

(a)

Interpretation Introduction

Interpretation:

Conditional formation constant for Mg(EDTA)2− at pH 9.00 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 Kf'.

(b)

Interpretation Introduction

Interpretation:

Concentration of free Mg2+ at pH 9.00 in 0.050 M Na2[Mg(EDTA)] 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.
