Pick out the wrong statement:
The integral heat of solution of either components can not be calculated from heat of mixing data.
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.
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.
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.
