Measurements of volume changes on the formation of precipitates of carbonates and phosphates of cadmium(II) and calcium(II) in aqueous solutions
Abstract
Changes in volume on the formation of CdCO3, CaCO3, Cd3(PO4)2 and Ca3(PO4)2 in aqueous solutions have been measured at 298.2 K. A dilatometer which has optically flat discs has been used for separating solutions. Values of the volume changes per mole of divalent metal ions have been determined. Volume changes on ‘dehydration’ have also been estimated from the measured data.
