pHase® is a dry granular acid that easily dissolves in water. It is heat stable up to 800° F. Its chemical formula is NaHSO4. In water it dissociates into sodium, hydrogen and sulfate ions, all of which are beneficial in food systems. Sodium is a known flavor enhancer, hydrogen ion lowers pH, and sulfate has nutritional value.
It appears that the major problem preventing use of sodium sulfate decahydrate for thermal energy storage can be avoided by using the composition which is at or slightly to the water-rich side of the invariant point in the phase diagram. A mixture of 68.2 w/o Na/sub 2/SO/sub 4/ x 10H/sub 2/O and 31.8 w/o H/sub 2/O is suggested for a TES material.

Abstract. Sodium sulfate phase III as a metastable and anhydrous phase of sodium sulfate and its properties are presented.. Occurence. The phase was observed next to thenardite during the evaporation of sodium sulfate solutions above 32.4 °C which is above the transition temperature of mirabilite to thenardite. The amount of metastable phase III increases with increasing …
However, the organic solvent layer (pesticide extract) still contains some residual water, which can adversely affect separation procedures that follow, such as solid-phase extraction and/or gas chromatography. Drying agents, such as sodium sulfate or magnesium sulfate, are used to remove the water from the organic extracts.
Hi Zakaria, I guess the sodium sulfate is to increase the overall ionic strength of the solvent - you have a anionic sulfate group in your buffer system and on the sodium hexane sulfonate. Analyte ...

The mobile phase initialy comprises Na2SO4, Sodium octane sulfonate, Tetrahydrofuran, Water and is used for the analysis of aminoglycosides. x g/L Na2SO4 is the overall conc in the mobile phase, not the conc of the aqueous part only. In the experiements I mentioned, only the amount of Na2SO4 is changed. In both cases, the necessary amount of ...
Aluminum sulfate – sodium sulfate – water. The phase diagram and experimental data at 42 °C are shown. Soda alum is precipitating on one of the three branches of this phase diagram. The solubility of soda alum is significantly higher than that of potassium alum. Aluminum chloride – potassium chloride – hydrochloric acid – water.
Sodium sulfate anhydrous disassociates in water to provide sodium ions and sulfate ions. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. What is sodium acid sulphate? pHase™ – Sodium Acid Sulfate is a natural acid that lowers pH without a sour taste.

Smooth phase transition from the liquid to solid phase and vice versa is essential for effective heat exchanger; however, supercooling in salt hydrates delays the onset of liquid–solid phase transition. We investigate the molecular level mechanism of supercooling in sodium sulfate decahydrate (SSD).
Sodium sulfate phase III Na 2 SO 4 metastable Sodium sulfate heptahydrate Na 2 SO 4 •7H 2 O metastable Mirabilite Na 2 SO 4 •10H 2 O Occurrence. Both thenardite and mirabilite occur as natural minerals. In nature sodium sulfate occurs in mineral waters in the form of double salts, as deposits of former salt lakes.
Water and salt phase change in sodium sulfate soil based on differential scanning Soils and Foundations ( IF 2.436) Pub Date :, DOI: 10.1016/j.sandf.2020.12.006 Xusheng Wan, Changmao Zhong, Zhaohui Yang, Enxi Qiu, Mengfei Qu, Songbo Wu, Li Liu
The stress generated by confined crystal growth in pores results in strain of a porous material, thus, strain measurement is an appropriate experimental approach to study salt-induced stress in a crystallization experiment (Espinosa et al., 2008, Ruedrich and Siegesmund, 2007, Steiger et al., 2008).In this study, digital dial indicators (Mahr 1083/1085, Germany) were used …
Sodium sulfate ... is a strong contributor to the rate of corrosion. For example, in water with 400 mg/l of alkalinity (as CaCO3) at pH 7, the corrosion rate will be zero at 200 mg/l of Na2SO4, but when the concentration of sodium sulfate is 400 mg/l, the corrosion rate will be about 100 mg per square cm per day.

Sulphate ions induce severe chemical deterioration in a cement matrix due to expansive product (e.g. ettringite and gypsum) formation or sodium sulphate crystallization. Considerably high sodium sulphate concentration can cause U-phase [(CaO)4(Al2O3)0.9(SO3)1.1(Na2O)0.5:16H2O] formation, which leads to increased …
