Question

Chapter 16, Problem 134AP

Interpretation Introduction

Interpretation:

The volume of the strong base required to neutralize two weak acids, out of which one acid is slightly stronger than the other, is to be determined.

Concept introduction:

When a weak acid is titrated against a strong base, the millimoles of acid and base are used to determine the complete neutralization of the acid, irrespective of its strength. The strength of the acid is taken into account to calculate the equivalence pH of the solution.

Gram equivalent of acid and base should be equal for complete neutralization.

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
