THE THERMODYNAMIC FUNCTIONS FOR THE SOLUTION OF CALCIUM HYDROXIDE IN WATER

THE SOLUBILITY PRODUCTS FOR CALCIUM HYDROXIDE WERE EVALUATED FROM THE SOLUBILITY AS A FUNCTION OF IONIC STRENGTH, PH AND TEMPERATURE. FROM THESE DATA THE STANDARD THERMO-DYNAMIC FUNCTIONS WERE DERIVED. THE LATTICE ENERGY OF CALCIUM HYDROXIDE IS -562 KCAL./MOLE WHEN CALCULATED BY MEANS OF THE BORN EXPRESSION. A BORN-HABER CYCLE GAVE A VALUE OF 77 KCAL./MOLE FOR THE ELECTRON AFFINITY OF THE HYDROXYL ION AND A HEAT OF HYDRATION OF 98 KCAL./ MOLE FOR THE GASEOUS HYDROXYL ION. AT 25 C THE SOLUBILITY PRODUCT IS GIVEN. /PCK/
