Abstract
A gravimetric analysis using meta-boric acid (HBO2 or DBO2) as a weighing form has been developed for solubility measurement. The method gave satisfactory results in preliminary measurement of solubilities of boric acid in light water. By using this method, the solubilities of 10B enriched D3 BO3 in heavy water were measured. The results are as follows; 2.67 (7°C), 3.52 (15°C), 5.70 (30°C), 8.87 (50°C) and 12.92 (70°C) w/o, respectively. These values are about 10% lower than those in light water. Thermodynamical consideration based on the data shows that boric acid is the water structure breaker.
