Precipitation and Solubility of Calcium Hydrogenurate Hexahydrate
Solid phases formed in the quaternary system: uric acid-calcium hydroxide -hydrochloric acid-water aged for 2 months at 310 K were studied to determine conditions for calcium hydrogenurate hexahydrate, Ca(C5H3N4O)2 · 6H2O precipitation. The precipitates were identified by chemical and thermogravimetric analyses, x-ray powder diffraction, infrared spectroscopy, light microscopy, and scanning ele...
متن کاملThe Apparent Solubility of Calcium Carbonate in Soils·
was dissolved from the soil; Le., equilibrium was ap Soils in the laboratory were reacted with agricultural drainage and distilled waters at various carbon dioxide (COl) levels. The soil water solutions yielded different Ion activity product (lAP) values than that of calcite, depending on experimental technique and whether calcite "equilibrium" is approached from supersaturation or under sat...
متن کاملThe effect of phosphate on the solubility of calcium carbonate and of bicarbonate on the solubility of calcium and magnesium phosphates.
In 1925, Holt, La Mer, and Chown (1) reported that the apparent solubility product [Ca++13[P04=J2 was greater in a solution of inorganic salts approximating the composition of serum than it was in solutions of sodium chloride of the same ionic strength. Very shortly thereafter, Sendroy and Hastings (2) recalculated values for pK’, Ca,(PO& from the data of Holt, La Mer, and Chown and also report...
متن کاملSolubility of calcium phosphates.
Solubil ity is one of the most important properties of calcium phosphate salts. It is the solubil ity that determines the direction of many reactions that involve calcium phosphates such as dissolution, precipitation, hydrolysis, and phase transformation. Calcium phosphate solubil ity also plays a maior role in biological processes that involve formation and resorption ol' hard tissues as well ...
متن کاملComparison of Phosphate Lowering Properties of Calcium Acetate and Calcium Carbonate in Hemodialysis Patients
Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...
