Cr(NO3)3.9H2O(s) = Cr(3+)(aq) + 3NO3(1-)(aq)

if it is born-haber cycle in question you will need to show intermediate step where lattice enthalpy is resupplied to give isolated gaseous ions that are then hydrated to give the electrolytic solution

p.s. if this helps rep me please - i need to get back on track
