Write shot notes on the Heat of solution.

The standard heat of formation of sodium ions in aqueous solution from the following data : Heat of formation of NaOH(aq) at 25^(@)C = - 470.7 KJ : Heat of formation of OH^- at 25^(@)C = -228.8 KJ is :

The heat of formation is the change in enthalpy accompanying the formation of a substance fiom its elements at 298 K and 1 atm pressure. Since the anthalpies of elements are taken to be zero, the heat of formation (triangleH) of compounds

The magnitude of heat of solution ….. On addition of solvent to solution

What will be the heat of formation of ethane, if the heat of combustion of carbon is -x kJ ,heat of formation of water is -ykJ and heat liberated during complete combustion of ethane is zkJ

The process in which the crystals of a solute are separated on cooling a hot saturated solution is called _______
