Chemistry - Liquid Solution Question with Solution | TestHub

So the enthalpy of solution can either be endothermic, exothermic or neither $(\Delta$ Hsolution $=0)$, depending on how much heat is required or release in each step. If $\Delta$ Hsolution $=$ 0 , then the solution is called an ideal solution and if $\Delta$ Hsolution $>0$ or $\Delta$ Hsolution $<0$, then these solutions are called non-ideal solutions. Related Theory The enthalpy of solution depends on the strengths of intermolecular forces of the solute and solvent. If the solution is ideal, and $\Delta \mathrm{H}$ solution $=0$, then $\begin{array}{rl}& \Delta H_{\text{solution }}=\Delta H_1+\Delta H_2+\Delta H_3=0\\ & \Delta H_1+\Delta H_2=-\Delta H_3\end{array}$
