And we'll see that in a second. Now, before we talk about that, let's talk about the heat of solution. Now, we have already spoken about heat of solution in another video, so let's briefly discuss it. So the heat of solution is the sum of energy required to break the intermolecular forces of compound one. Plus the sum of the energy is required to break the intermolecular forces of compound two plus the energy release when you form the new solution. And that gives you the enthalpy of solution or heat of solution.
