Ideal solution
From Academic Kids
In chemistry, an ideal solution is a solution where the enthalpy of solution is zero. The closer to zero the enthalpy of solution is, the more "ideally" the solution behaves. This becomes important in properties such as colligative properties, where the calculated values hold truer the more ideal the solution. How ideally a solution is is analogous to how ideally a gas behaves, as described in the kinetic theory of matter.
