Abstract
The solubility of silver chromate in water has been studied between 5 and 80�C. Conductometric, spectrophotometric, tracer, and pH measurements were used to evaluate and confirm the solubility product as 2.76x10-12�3% at 298 K and ���������������������� ��ΔH0 = 93700-0.393T2 J (mol Ag2CrO4)-1 ������������������������ ΔS0 = 210-0.79T J K-1 (mol Ag2CrO4)-1 In contrast to some previous work, particles having approximate dimensions of 0.5 μm were found to have the same solubility as larger crystals. Tracer-level labelling (specific activity 1 and 2mCi (gAg2CrO4)-1 of 110mAg) with self irradiation for times as long as six months did not change the solubility. The measurements were dependent on the level of illumination.Keywords
