How do you measure heat of hydration

Question

Accepted Answer

Heat of hydration can be measured using calorimetry.

Calorimetry involves measuring the heat released or absorbed during a chemical reaction.
The heat of hydration can be calculated by subtracting the heat released by the reaction of the anhydrous compound with water from the heat released by the reaction of the hydrated compound with water.
For example, the heat of hydration of calcium chloride can be measured by reacting anhydrous calcium chloride with water and measuring the heat released, then reacting hydrated calcium chloride with water and measuring the heat released, and finally subtracting the two values.
Another method involves using a bomb calorimeter to measure the heat of hydration directly.
The heat of hydration is an important property to consider in the design and construction of concrete structures.
