When lithium fluoride dissolves in water, the temperature of the
resulting solution decreases. This means that for lithium fluoride,
the enthalpy of hydration is:
the same magnitude as the lattice energy
smaller(magnitude) than the lattice energy
larger (magnitude) than the lattice energy
Homework Answers
Enthalphy of dissolution = lattice energy + enthalphy of hydration
Lattice energy value is +ve
enthalphy of hydration is -ve
when temperature of resulting solution decreases it indicates heat is asborbed from solution. This indicates endothermic reaction i,e enthalphy of dissolution is +ve
This will happen if enthalphy fo hydration is smaller in magnitude that the Lattice energy

When lithium iodide (LiI) is dissolved in water, the solution becomes hotter. [ Hint: According to Hess’s Law, the overall enthalpy change upon solution formation is the sum of the changes in enthalpy for each step. Recall which two terms on the right hand side of the equation below combine to make the heat of hydration. ] Hsolution = Hsolute + Hsolvent + Hmixing a.) Is the dissolution of LiI endothermic or...

The deltaH for the solution process when solid sodium hydroxide dissolves in water is 44.4 kJ/mol. When a 13.9g sample of NaOH dissolves in 250.0 g of water in a coffee-cup calorimeter, the temperature increases from 23.0°C to ? . Assume that the solution has the same specific heat as liquid water, i.e., 4.18 J/g-K.
