Concept explainers
Interpretation:
The ions or molecules present in the aqueous solution of the oxalic acid are to be determined. The identification of the ion that is present in the lowest concentration id to be done.
Concept Introduction:
The chemical substance which releases hydrogen ion in the solution is known as acidic substance. In such compounds, the hydrogen atom is attached to an electronegative atom. Thus, it readily loses hydrogen ions in the solution.

- 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.
