Enthalpies of solution

Question 1

How does water dissolve an ionic lattice?

Answer 1

The partially positively charged hydrogen attracts the negative ions in the lattice
The partially negatively charged oxygen attracts the positive ions in the lattice

Question 2

How do you calculate enthalpy change of solution?

Answer 2

Lattice dissociation + enthalpies of hydration

Question 3

How do you calculate lattice dissociation?

Answer 3

Enthalpy change of solution - enthalpies of hydration

Question 4

How do you calculate enthalpies of hydration?

Answer 4

enthalpy change of solution - lattice dissociation
