7681-38-1 Usage

General Description

Sodium bisulfate, also known as sodium hydrogen sulfate, is a white crystalline solid that is highly soluble in water. It is an acidic salt and is often used as a pH adjuster in various industrial and household applications. In addition to its ability to lower the pH of a solution, sodium bisulfate is also used as a cleaning agent and sanitizer in various cleaning products. It is commonly found in household cleaners, swimming pool chemicals, and as a food additive for preserving and enhancing flavor. Sodium bisulfate is considered safe for use in these applications when handled and used appropriately. Additionally, it is an environmentally friendly alternative to other harsher chemicals, making it a popular choice in many industries.

Check Digit Verification of cas no

The CAS Registry Mumber 7681-38-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7681-38:
(6*7)+(5*6)+(4*8)+(3*1)+(2*3)+(1*8)=121
121 % 10 = 1
So 7681-38-1 is a valid CAS Registry Number.

Bi-functional RuO2-Co3O4 core-shell nanofibers as a multi-component one-dimensional water oxidation catalyst

Ko, Jong Wan,Ryu, Won-Hee,Kim, Il-Doo,Park, Chan Beum

, p. 9725 - 9727 (2013)

The core-shell structure of RuO2-Co3O4 fibers comprising the inner region of highly conductive RuO2 and the outer region of catalytic Co3O4 provided a fast and effective transport pathway for holes to O2-evolving sites, leading to a highly efficient water oxidation performance.

Phase transition between two anhydrous modifications of NaHSO4 mediated by heat and water

Zangmeister, Christopher D.,Pemberton, Jeanne E.

, p. 1826 - 1831 (2007)

The phase transition between the two anhydrous modifications of NaHSO4 (α and β) was studied using Raman spectroscopy and differential scanning calorimetry. These measurements indicate that β-NaHSO4 is a metastable phase and readily undergoes phase transition to thermodynamically stable α-NaHSO4 with an exothermic enthalpy change of 3.5 kJ/mol. Both thermal (temperatures >434 K) and chemical (exposure to H2O) pathways were identified for this transition. The transition is irreversible, and α-NaHSO4 is an intermediate phase between β-NaHSO4 and NaHSO4·H2O. The possible mechanism of the phase transition is discussed.

Kinetics of the autoxidation of sulfur(iv) co-catalyzed by peroxodisulfate and silver(i) ions

Doka, Eva,Lente, Gabor,Fabian, Istvan

, p. 9596 - 9603 (2014)

The kinetics and mechanism of the reaction between dissolved oxygen and sulfur(iv) was studied in aqueous acidic medium using co-catalysts peroxodisulfate and silver(i) ions. The presence of both catalysts was required to observe measurable rates in the studied process. The reaction rate was determined through following the UV-absorption of hydrated sulfur dioxide, and the trends were determined as a function of pH, reactant and catalyst concentrations. Individual kinetic curves under conditions where dissolved oxygen was the limiting reagent were close to zeroth-order. A chain mechanism with four chain carriers, sulfite, sulfate, peroxomonosulfate ion radical and silver(ii) ion, is proposed to interpret all the kinetic and stoichiometric findings, and an explicit formula was obtained for the rate law. The role of the co-catalysts is to produce chain carriers, whereas silver(i) and silver(ii) ions also participate in chain propagation steps. Further supporting evidence for the proposed mechanism was gained in laser flash photolysis studies, which showed that sulfate ion radical reacts quite rapidly with silver(i) ion.

Method for comprehensively utilizing dehydrated dilute sulphuric acid and byproduct sodium chloride and producing byproduct sodium hydrogen sulfate

-

Paragraph 0012, (2017/04/03)

The invention provides a method for comprehensively utilizing dehydrated dilute sulphuric acid and byproduct sodium chloride and producing byproduct sodium hydrogen sulfate. The method comprise the following steps: feeding dehydrated dilute sulphuric acid and byproduct sodium chloride in a production process for producing glyphosate by virtue of a glycine method into a reaction kettle, and carrying out heat preservation reaction; cooling a gas phase to 28-33 DEG C by virtue of a condenser, and introducing the gas phase into a four-stage hydrochloric acid absorption tower in a dimethyl phosphite production process; and carrying out filtration, cooling crystallization, centrifugal separation and drying on reaction liquid, so as to obtain the finished product sodium hydrogen sulfate. By virtue of the method, the treatment problem of dehydrated dilute sulphuric acid and byproduct sodium chloride is solved, and the resource comprehensive reutilization of byproducts including dilute sulphuric acid and sodium chloride in the production of glyphosate is realized.

Quantum yield measurements for the photocatalytic oxidation of Acid Orange 7 (AO7) and reduction of 2,6-dichlorindophenol (DCIP) on transparent TiO2 films of various thickness

Krysa,Baudys,Mills

, p. 132 - 137 (2015/02/19)

This work comprises the photoactivity assessment of transparent sol-gel TiO2 coatings of various thickness using two test systems. The initial rates of both photocatalytic reactions, namely the oxidative bleaching of Acid Orange 7 (AO7) and the reductive bleaching of 2,6-dichlorindophenol (DCIP) increase linearly with increasing titania film thickness as well as with increasing absorbed light flux. The latter work revealed quantum yields (QY) of 0.19% and 92% for the AO7 and DCIP test system, respectively. The low QY for the AO7 oxidation is due to the combination of a slow irreversible reduction of oxygen and also for the oxidation of AO7, thus favouring the high efficiency for electron-hole recombination that is typical for aqueous organic pollutants. In contrast, the very high QY for the photocatalysed reduction of DCIP is due to the presence of a vast excess of glycerol which traps the photogenerated holes efficiently and so allow time for the slower reduction of dye to take place. Furthermore, the oxidation of glycerol results in the generation of highly reducing R-hydroxyalkyl radicals that are able to also reduce DCIP. As a consequence of this 'current doubling' effect, the observed QY (92%) is much higher than the apparent theoretical value of 50%.
