Complete question:
When lithium iodide is dissolved in water, the solution becomes hotter.
What can you conclude about the relative magnitudes of the lattice energy of lithium iodide and its heat of hydration?
Answer:
The heat of hydration is greater in magnitude than the lattice energy and lattice energy is smaller in magnitude that the heat of hydration.
Explanation:
When the solution becomes hotter on addition of lithium iodide, it shows exothermic reaction and it means that the heat of hydration is greater than the lattice energy and lattice energy is smaller in magnitude that the heat of hydration.
This can also be observed in the formula below;
[tex]H_{solution} = H_{hydration} + H_{lattice. energy}[/tex]
Heat of the hydration is thus greater in magnitude than that of the lattice energy and the lattice energy is smaller in the magnitude than the heat of hydration.
The lattice energy is defined as the energy needed to separate the mole of the icon into a slid gaseous ion. It can be measured empirically and is calculated by use of electrostatics.
The heat of hydration is the great energy generated when the water reacts with the contact of cement powder. This leas to high temperatures and cause thermal cracking and the reduction of mechanical properties.
