(a)
Interpretation:
The formula of an ionic compound chromium sulphate should be written.
Concept Introduction:
An ionic compounds to be electrically neutral, the sum of the charges on the cation and anion is must be zero. If the charges on the cation and anion are numerically different, the following rule can be applied to make the compound electrically neutral.
“The subscript of the cation is numerically equal to the charge on the anion and vice versa’’
If the charges on the cation and anion numerically equal, then no subscripts need.
(b)
Interpretation:
The formula of an ionic compound Titanium oxide should be written.

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.
