Solubility of Calcium Phosphates

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications This agent can be used as a countermeasure for exposure to strontium and radium radionuclides Upon oral uptake calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium in the gastrointestinal (GI) tract Calcium oxalate is an ionic compound with the chemical formula CaC2O4 and a salt of oxalic acid It's highly insoluble and dissolves poorly in water One method for dissolving calcium oxalate in the lab is the application of a compound called ethylenediaminetetraacetic acid or EDTA EDTA is highly effective at

Influence of Metal Ions on the Crystal Growth of Calcium

Calcium Phosphates in Biological and Industrial Systems The main inorganic chemical component of bone and teeth is calcium phosphate which is deposited through careful control by the development of a slight excess of the solubility product 1

When making prescriptions for total parenteral nutrition (TPN) it is necessary to take into consideration also substitution with calcium and phosphorus Under some clinical conditions or in certain groups of patients it is necessary to supply these substances in high doses with a reduced volume which due to mutual interactions may be problematic

Solubility of calcium 2

SOLUBILITY OF CALCIUM 2 METHYLBUTYRATE IN WATER By David F Houston ABSTRACT This paper presents new data for the solubility of calcium 2-methylbutyrate in water from 0 to 100 C Earlier information concerning the solubility and hydra tion of this salt is compared with the present results A transition from the

Amorphous calcium phosphates (ACPs) represent a unique class of biomedically relevant calcium orthophosphate salts in which there are neither translational nor orientational long-range orders of the atomic positions Nevertheless the constancy in their chemical composition over a relatively wide range of preparation conditions suggests the presence of a well-defined local structural unit

Processed cheese requires a calcium sequestering agent to remove calcium from the casein micelle of the cheese in order to emulsifiy the fat and turn the casein into a thermal plastic material In addition the citrates and/or phosphates provide a buffering capacity to stabilize the system in the pH range of 5 4-5 6 Blends of phosphates and citrates most commonly used singly or in combination

OBJECTIVES Calcium and phosphate incompatibility in parenteral nutrition formulations remains a critical concern for patient safety This study examined calcium phosphate solubility for 2-in-1 admixtures prepared using 2 commercially available pediatric amino acid solutions (Premasol Baxter Healthcare Corp or Trophamine B Braun Medical Inc) applying identical test methods storage

Monobasic Calcium Phosphate (MCP) Ca(H 2 PO 4) 2 and Monobasic Magnesium Phosphate (MMgP) Mg(H 2 PO 4) 2 are widely used as fertilizers They have the drawback of being only slightly soluble in water whereas such fertilizers are usually applied in aqueous solutions However solubility while essential is not the only property required

The determination of the solubility of calcium phosphates by the conventional large excess of solid method has been demonstrated to be inappropriate The problem lies in incongruent dissolution leading to phase transformations and lack of detailed solution equilibria: all calculations have been based on simplifications which are only crudely approximate The absolute solid-titration

Thus a higher solubility of both calcium orthophosphates and calcium carbonate in very weak acids was a well-known fact The solubility data were updated in a publication of 1855 [ 69 ]: "Apatite dissolves in 393 000 parts of water saturated with carbonic acid Artificial neutral phosphate freshly precipitated in 1 503 parts Artificial basic phosphate freshly precipitated in 1 102

Biological and Medical Significance of Calcium Phosphates Sergey V Dorozhkin and Matthias Epple* Dedicated to Professor Sir John Meurig Thomas on the occasion of his 70th birthday The inorganic part of hard tissues (bones and teeth) of mammals consists of calcium phosphate mainly of

Octacalcium phosphate (OCP) has been reported to stimulate bone regeneration during hydrolysis into hydroxyapatite (HA) The present study was designed to characterize structural morphological and surface properties of fluoride-containing apatitic calcium phosphates (CaP) obtained through OCP hydrolysis or direct precipitation of OCP in the presence of 12-230 ppm of fluoride (F)

The equilibrium solubility of four calcium salts (calcium oxalate hydrate calcium citrate tetrahydrate calcium phosphate calcium glycerophosphate) were determined at controlled pH values (7 5 6 0 4 5 and or = 3 0) and in distilled water

Combinations of sparingly soluble calcium phosphates in slurries and pastes as mineralizers and cements May 9 1985 - American Dental Association Health Foundation Dental restorative compositions containing a mixture of Ca sub 4 (PO sub 4) sub 2 O and at least one different calcium phosphate

Solubility is known to be one of the main factors which control availability of phosphates but there is now conclusive evidence as to the importance of physiological availability Some investigators (26 13)1 have produced evidence which they claim supports the hypothesis that the H2PO4- ion is the only phosphate ion absorbed by plants

The fouling characteristics of artificially hardened waters containing calcium and orthophosphate ions were investigated The water was circulated through a steam heated double pipe heat exchanger under turbulent flow conditions Inlet water temperatures were about 20 to 25C and the phosphate content about 100 ppm Experiments were carried out to ascertain the effects of pH velocity

Solubility is the property of a solid liquid or gaseous chemical substance called solute to dissolve in a solid liquid or gaseous solvent The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature pressure and presence of other chemicals (including changes to the pH) of the solution
