WebThe formula is. H = H 1 – H 2 – 0.4 (t h – 25.0) H = heat of hydration of ignited cement, kJ/kg, H 1 = heat of solution of dry cement, H 2 = heat of solution of a partially hydrated sample, and. th = final calorimeter temperature at end of determination on the partially hydrated sample, °C. WebIt can be considered as enthalpy of solvation with the solvent being water. Hydration enthalpy is also called hydration energy and its values are always negative. For a …
