How is this Possible GK. Everywhere I have looked, including mark schemes and chemistry websites dH(solution) is worked out via this equation: dH(solution) = dH(LE) - dH(hyd) + dH(hyd) What is it you are working out with solute and solvent?

**Chemistry College (Need to know!)**

Am I Correct in assuming this? dH of solution = -dH of lattice enthalpy + dH of hydration E.g: dHsolution NaCl = -dHLE NaCl(s) + dHhyd Na+(g) + dHhyd Cl-(g) Units as kJmol-1
