This site provides an excellent overview of the solution process. Content includes a focus on how a solution is formed, energy changes and solution formation, spontaneity and disorder, and solution formation and chemical reactions.

Determine the heat of solution for various salts.

The students discover the basics of heat transfer in this activity by constructing a constant pressure calorimeter to determine the heat of solution of potassium chloride in water. They first predict the amount of heat consumed by the...

This resource provides a physical reaction. Hydrous and anhydrous calcium chloride react with water to produce physical exothermic and endothermic reactions.

A detailed discussion of solubility as a function of Enthalpy and Entropy. Goes way beyond the standard solubility discussion.

An animation to investigate the rates of heating or cooling in a calorimeter. Also, molar enthalpy of solution of sulfuric acid is discovered.

This activity provides a demonstration of Hess's Law using three reactions: the solubility NaOH in water, the solubility NaOH in HCl, and the reaction of a solution of HCl and a solution of NaOH.

Measure the enthalpy of a reaction and then create a solution warm enough to cook food.

In this part of the MRE scenario, students create solutions that when mixed, increase to a certain temperature.

In this activity, students use knowledge of specific heat capacity to mix together hot coffee and cold milk to create a solution of coffee at a desired temperature. In this randomized problem, each student is given a different final...
