Chapter 25, Problem 25.3P
Interpretation Introduction

Interpretation:

The percentage of the un-ionized form, mono-anion form, and the di-anion form for methyl phosphate at pH 7.4 are to be determined.

Concept introduction:

There are two protons in methyl phosphate which can dissociate. So, there are three forms which are un-ionized form (charge = 0), mono-ionized form (charge = -1) and di-ionized form (charge = -2).

If the value of pH is more than pKa, this indicates that the acid is about 99% dissociated.

If the value of pH is one unit higher than that of pKa, this indicates that the acid is about 90%

1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)
