the relationship (if any) of the lattice energy of compounds
Not what you're looking for?
Hello:
I need help understanding the relationship (if any) of the lattice energy of compounds such as ZnO vs. H3BO3 vs. their respective solubilities.
For instance, at neutral pH and standard conditions, I'm trying to understand why ZnO is much much less soluble in water than is H3BO3 --- is it possible because of a difference in lattice energies and how would I determine and calculate the lattice energies?
Thank you

Lattice energy refers to the measure of strength of bonds in a given ionic compound and can be defined as the energy required separating the ions of the ionic compound in its gaseous state. It depends upon the ionic charge as well as the ionic radius. In other terms, more the charge on ions more will be the lattice energy whilst smaller the radius of ions, more will be the lattice energy (as ions come closer to each other and hence force of attraction increases). It is given as symbol U.
The solubility of a substance is dependent on the ...
