Interpretation Introduction

Interpretation: The mass percentage of the solution has to be calculated.

Concept Introduction:

The changes in boiling and freezing point are by given by the modified equation that is used to determine the colligative properties of strong electrolytes. The van’t Hoff factor in the equation is given by,

ΔT=imK

Where, K= change in boiling/freezing point

i=Van’t Hoff factor that takes the equation,

i=moles of particles in solutionmoles of solute dissolved

Mass percent of compound can be given by calculated mass of the compound to the total mass whole multiplied by 100 .

Mass percent(%)=Calculated mass(g)Total mass(g)×100

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.
