Horstmann (1869-72) showed that the dissociation pressures of sal ammoniac, sodium phosphate hydrate, and calcium carbonate obey the same law as that for the vapour pressure of a liquid, the heat of dissociation Q being substituted for the heat of evaporation or sublimation in the equation deduced by Clapeyron and Clausius ... 

The solubihty of a number of sodium orthophosphates is depicted in Figure 7. Some of the sodium phosphates dissolve or precipitate incongmendy, affording a different Na20/P20 ratio in the solution phase from that of the soHd phase. Sodium phosphates that precipitate are also a function of the temperature. As the temperature increases, the sodium phosphates that may precipitate from solution tend to be anhydrous or lower hydrates than those equiUbrium sodium phosphate phases at lower temperature. Whereas most of the phases in Figure 7 represent congmentiy soluble sodium phosphates, soHd phases appear or disappear upon changes in temperature. 

About 264,000 metric tons of elemental capacity is available in North America, plus another 79,000 t (P equivalent) of purified wet phosphoric acid (14). About 85% of the elemental P is burned to P2 5 hydrated to phosphoric acid. Part of the acid (ca 21%) is used direcdy, but the biggest part is converted to phosphate compounds. Sodium phosphates account for 47% calcium, potassium, and ammonium phosphates account for 17%. Pinal apphcations include home laundry and automatic dishwasher detergents, industrial and institutional cleaners, food and beverages, metal cleaning and treatment, potable water and wastewater treatment, antifree2e, and electronics. The purified wet acid serves the same markets.

The production of a baking powder depended on a system where the reaction could be delayed until required. In 1864 a patent was taken out to use monocalcium phosphate hydrate in making a baking powder. In 1885 sodium aluminium sulfate came to be used. This compound has a low solubility in water at ambient temperatures so it does not start to act until the product has heated up. 

Sodium phosphate is available as a nonprescription liquid formulation and by prescription as a tablet formulation. When taking these agents, it is very important that patients maintain adequate hydration by taking increased oral liquids to compensate for fecal fluid loss. Sodium phosphate frequently causes hyperphosphatemia, hypocalcemia, hypernatremia, and hypokalemia. Although these electrolyte abnormalities are clinically insignificant in most patients, they may lead to cardiac arrhythmias or acute renal failure due to tubular deposition of calcium phosphate (nephrocalcinosis). Sodium phosphate preparations should not be used in patients who are frail or elderly, have renal insufficiency, have significant cardiac disease, or are unable to maintain adequate hydration during bowel preparation.

Other applications of fluidization have been made to such materials as sodium chloride liable salt), soda ash. sodium phosphate, sodium sulfate, starch, talc, magnesium oxide, dry clay, bone acid, hydrated lime, and various high polymers in powdered or head" form. Fluidization is especially effective in loading and unloading materials from railroad cars and trucks, as well as in moving them aboul within the plant.

Sodium Phosphate, Monobasic, is anhydrous or contains one or two molecules of water of hydration and is slightly hygroscopic. The anhydrous form occurs as a white, crystalline powder or granules. The hydrated forms occur as white or transparent crystals or granules. All forms are freely soluble in water, but are insoluble in alcohol. The pH of a 1 100 solution is between 4.1 and 4.7. 

Sodium Phosphate, Tribasic, occurs as white crystals or granules or as a crystalline material. It may be anhydrous or contain 1 to 12 molecules of water of hydration. The formula for a crystalline material is approximately 4(Na3P0412H20)-NaOH. It is freely soluble in water, but is insoluble in alcohol. The pH of a 1 100 aqueous solution is between 11.5 and 12.5. 

Sodium phosphites.—Disodium hydrogen phosphite, Na2HP03,5H20, is obtained by concentration of a solution of phosphorous acid neutralized with sodium carbonate, and over sulphuric acid changes to the anhydrous salt. The pentahydrate is very deliquescent. The anhydrous salt melts at 53° C., and above this temperature is oxidized to sodium phosphate, with evolution of phosphine.7 The heat of formation from the elements is 285 1 Cal.,8 and from the acid and sodium hydroxide in solution 28 45 Cal.9 The heat of hydration of the anhydride to the pentahydrate is 18 7 Cal.
