Sodium hydrogen phosphates

The alphabetical order may be different in formulas and names for example, NaNH4HP04, ammonium sodium hydrogen phosphate. 

Sodium hydrogen phosphate, Na2HP04 I2H2O—Q.5N-. 60 g liter. 

Other additives that may be incorporated include sodium hydrogen phosphates as buffering agents to stabilise that pH of the reaction medium, lauryl mercaptan or trichlorethylene as chain transfer agents to control molecular weight, a lubricant such as stearic acid and small amounts of an emulsifier such as sodium lauryl sulphate.

The sample is then leached with the addition of a 10% aqueous solution of sodium hydrogen phosphate/sodium bicarbonate at 55°C for 15 min. 

Diphasic liquid systems used in CCC may have a wide variety of polarities. The most polar systems are the ATPS made by two aqueous-liquid phases, one containing a polymer, for example, polyethylene glycol (PEG), the other one being a salt solution, for example, sodium hydrogen phosphate. The less polar systems do not contain water there can be two-solvent systems, such as heptane/acetonitrile or dimethylsulfoxide/hexane systems or mixtures of three or more solvents. Intermediate polarity systems are countless since any proportion of three or more solvents can be mixed. Ternary phase diagrams are used when three solvents are mixed together.

What do you observe Write the equations of the reactions and explain how the medium affects the course of the process. 

Condensed polyphosphates such as sodium triphosphate are of great industrial importance since they arc used in large tonnages as "builders" in the manufacture of detergents. As such they function to adjust the pH and to complex water-hardening ions such as Ca2+ and Mg2+.17 Industrially, sodium triphosphate is rot made from the reaction of Eq. 16.12 but from dehydration of sodium hydrogen phosphate and sodium dihydrogen phosphate mixtures ... 

The orthophosphates.—Orthophosphoric acid forms three salts, normal or tertiary, secondary, and primary phosphates, according as all, two, or one of its hydrogen atoms is replaced by an equivalent radicle.26 The hydrogen atoms may be replaced by different radicles. Thus, the secondary acid salt—ammonium sodium hydrogen phosphate, also called microcosmic salt—is illustrated by the subjoined graphic formula along with the formulae for the acid and the primary, secondary, and tertiary sodium salts ... 

Before extraction, sample was added with 1 M sodium hydrogen phosphate and i.s. 

In subsequent experiments, using other crystal systems, such as ferrous sulfate and sodium hydrogen phosphate, it was similarly observed that the first crystallization product to form was the one most closely resembling the structure of the solvent (Nyvlt, 1995). For the case of citric acid, this is the monohydrate, which more closely resembles the aqueous structure. As the temperature of the solution is increased, the structure of the solvent, as well as the solubility of the crystal, changes, resulting in a more thermodynamically stable anhydrous product. This conversion between the kinetic and thermodynamic product occurs at a critical transition temperature, below which the structure of the solution favors the formation of the hydrated product. As the transition temperature is surpassed, the anhydrous product becomes favored. 

The photocatalyst was T1O2 Degussa P-25 (mainly anatase, specific surface area 50 m2 g-1). Ti02 in suspension was used in all photocatalytic experiments. Sodium hydrogen phosphate, sodium bicarbonate, sodium nitrate, sodium sulfate, sodium chloride, potassium sulfate, potassium bicarbonate, potassium hydrogen phosphate, potassium sulfate, potassium nitrate, potassium chloride, and iron chloride were used without further purification and were supplied by Fluka (Buchs, Switzerland).
