it has been a while since ive done these so i just need a refresher. im looking for the heat of hydration of lithium chloride and sodium chloride.

compound Lattice Energy deltaH soln
LiCl -834 kj/mol -37.0 kj/mol
NaCl -769 kj/mol +3.88 kj/mol

what is delta H hydration?

  • chemistry -

    dHsolution = dHsolvation - lattice energy
    -37 = dHhydration -(-834)

    thats right now i remember! i knew it wasn't hard but its been a while. thanks! so its just -871 for LiCl

  • chemistry -

    Looks like that.
