Enthalpy change when 1 mol solute dissolves completely
Enthalpy change: gaseous ions to 1 mol aqueous ions
Lattice breaks to gaseous ions; ions hydrate
Endothermic (energy needed to overcome attractions)
Exothermic (always releases energy)
Lattice + solution enthalpy = sum of hydration enthalpies
q=mcΔTq = mc\Delta Tq=mcΔT
Mass of solution (water + dissolved compound)
Positive (endothermic)
Endothermic dissolution absorbs heat from surroundings
