The discussion clarifies the distinction between heat of mixing and differential heat of dilution, particularly in the context of calcium chloride solutions. Heat of mixing refers to the total enthalpy change when two substances are combined, while differential heat of dilution is the slope of the heat of dilution curve at a specific molality. For obtaining heat of mixing values for calcium chloride solutions, resources such as Perry's Chemical Handbook and Elementary Principles of Chemical Process are recommended. Integral tables for heat of dilution provide necessary enthalpy changes relative to infinite dilution.
PREREQUISITESChemical engineers, researchers in solution chemistry, and students studying thermodynamics will benefit from this discussion, particularly those focusing on enthalpy changes in ionic solutions.
Typically, you get what are called Integral tables for heat of dilution. Such a table (as the one linked above) lists enthalpy changes (relative to infinite dilution, where h = 0) as a function of molality. So the heat of dilution to go from molality M1 to molality M2 is simply the difference between two values in the table, namely h(M1) - h(M2) and it would have units of say, kJ.ritunesh said:I want to know what's difference between heat of mixing and differential heat of dilution. I am working on calcium chloride solution. I need to know also from where i can get heat of mixing of calcium chloride solution.
