A. The integral heat of solution of either component cannot be calculated from heat of mixing
data
B. The average value of heat of neutralisation of dilute solutions of weak acids and bases is much
less compared to that for strong acids and bases
C. The standard heat of solution of the hydrate of a substance is the difference between the heat
of solution of the anhydrous substance and its heat of hydration
D. The accompanying enthalpy change, when a solute is dissolved in solvent, depends upon the
nature & amount of the solute & the solvent, on the temperature & on the initial & final
concentrations of the solution
