Abstract
When crystals of sodium dichromate dihydrate are heated at 1 atm pressure, the phase change Na2Cr2O7,2H2O → Na2Cr2O7,H2O + saturated solution occurs at 82.8°C with the absorption of 17.6±0.95 kJ per mole of dihydrate. A second phase change Na2Cr2O7,H2O → Na2Cr2O7 + saturated solution occurs at 91.1°C with the absorption of a further 12.4±1.5 kJ per mole of dihydrate.
