摘要
The optimum volume ratio of water. to acetone for Zn(Val)SO4.H2O crystalling from the mixed solvent of water with acetone has been determined, which is 1:10. The,crystal growth process of the compound at 298.15 K is investigated by microcalorimetry. The experimental results show that it obeys the Burton-Cabrera-Frank dislocation theory. Moreover, the enthalpy of solution of Zn(Val)SO4.H2O in water has been measured at 298.15 K. The standard enthalpy of formation of Zn(Val)(2+)(aq) has been calculated.
