The combined heat of hydration for the ions in potassium bromate (KBrO₃): -704kJ/mol.
Heat of hydration is the amount of heat released when 1 mole of combined ions of an electrolyte in excess amount of water.
Lattice energy is the energy required to separate 1 mole of an ionic solid into individual ions is gaseous state.
Heat off solution is (Enthalpy of solution) is the energy released when 1 mole of solid is dissolved in a solvent.
ΔH solution = ΔH lattice E + ΔH hydration
Enthalpy of solution and enthalpy of solution bears -ve signs and lattice bears +ve signs.
ΔH hydration = ΔH solution -ΔH lattice E
= 41.1 kJ/mol - 745kJ/mol
ΔH hydration = -703.9kJ/mol
