The heat of solution of complexes is equal to 0·25 eV and that of free CO 3 2− ions is higher than 1·2 eV. Under conditions of the thermal equilibrium between the solid solution and precipitate, the ratio of Na 2 CO 3 and CaCO 3 components in the precipitate has been calculated...
Heat the second beaker which contains the calcium chloride solution. Solid calcium chloride is the solid left after the water evaporates. Calcium Chloride Solutions Calcium chloride is highly soluble in water, because of its high solubility it is used to obtain solutions having relatively high densiti...
Soluble in water, meanwhile release a mass of heat, aqueous solution is subacidity. Soluble in alcohol, acetone, acetic acid. Act with ammonia ethyl alcohol, producing CaCl2 ·8NH3 and CaCl2 ·4C3H5OH complex. At normal temperature the aqueous solution crystallizes, sometimes is hexahy...
where Ca is the analyte concentration (solubility of CO2) in the brine (in mol.kg−1), Ct is the titrant concentration (in mol.L−1), Vt is the volume of titrant (mL), N is the molar ratio of analyte and reactant from a balanced chemical equation and Ma is the mass of the ...

Various thermodynamic properties (i.e., water activity, osmotic coefficient, mean ionic activity coefficient, enthalpy of dilution and solution, relative apparent molar enthalpy, heat capacity of aqueous phase and solid phases) are collected and fitted to the model equations. The thermodynamic ...
The molar enthalpy of transition of α-CaCl 2 ·4H 2 O to (CaCl 2 ·2H 2 O + aqueous solution) at 318.73 K is (30.6 ± 0.4) kJ·mol 1 . The molar enthalpy of fusion of FeCl 3 ·6H 2 O at 310.0 K is (54.5 ± 0.6) kJ·mol 1 . Lattice constants determined from Guinier ...
When ZnFe2O4 is subjected to chlorination using a M gCl2–CaCl2 mixture (MgCl2–CaCl2–ZnFe2O4 molar ratio = 1.5:1.5:1) at 950 °C for 120 min, the process results in a chlorination percentage of over 90% for Zn, with Fe chlorination percentage lower than 5%. ...
