Description
Sodium bisulfate monohydrate, also known as sodium hydrogen sulfate monohydrate, is an organic compound with the chemical formula H3NaO5S. It is a light yellow-colored crystalline sodium salt that has a characteristic odor and is moderately soluble in water. Sodium bisulfate monohydrate is acid soluble and serves as a source of sodium for various applications, particularly those compatible with sulfates.
Uses
1. Water Treatment Industry:
Sodium bisulfate monohydrate is used as a source of sodium for water treatment applications. The reason for its use is that most metal sulfate compounds, including sodium bisulfate, are soluble in water, making them suitable for water treatment processes.
2. Chemical Synthesis:
Sodium bisulfate monohydrate is used as a catalyst in various chemical synthesis processes, including:
a. Synthesis of n-butyl acetate: It acts as a catalyst in the production of n-butyl acetate, an ester commonly used as a solvent and in the flavor and fragrance industry.
b. Esterification reaction of primary and secondary alcohols with aliphatic carboxylic acids: Sodium bisulfate monohydrate facilitates the esterification process, which is essential for producing esters used in various industries such as pharmaceuticals, cosmetics, and the food industry.
c. Synthesis of iso-amyl acetate: Sodium bisulfate monohydrate is used as a catalyst in the synthesis of iso-amyl acetate, a flavoring agent and solvent.
d. Synthesis of herbicide, 2,4-D butylate (butyl 2,4-dichlorophenoxyacetate): Sodium bisulfate monohydrate plays a crucial role in the production of this herbicide, which is widely used in agriculture for weed control.
Precaution
Sodium bisulfate monohydrate is hygroscopic, thus may cause burns to eyes and skin. Moreover, it can cause respiratory and digestive tract burns.
Check Digit Verification of cas no
The CAS Registry Mumber 10034-88-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10034-88:
(7*1)+(6*0)+(5*0)+(4*3)+(3*4)+(2*8)+(1*8)=55
55 % 10 = 5
So 10034-88-5 is a valid CAS Registry Number.

Raman spectroscopy and atomic force microscopy of the reaction of sulfuric acid with sodium chloride
Zangmeister,Pemberton
, p. 12289 - 12296 (2000)
The reaction of NaCl with H2SO4 is investigated using Raman spectroscopy, atomic force microscopy (AFM), and gravimetric analysis. Raman spectra are consistent with the formation of NaHSO4 with no evidence for Na2SO4. The spectra indicate that the phase of NaHSO4 varies with the amount of H2O in the H2SO4. At low H2O concentrations, the reaction produces anhydrous β-NaHSO4, which undergoes a phase change to anhydrous α-NaHSO4 over the course of 18 h. At higher H2O concentrations, anhydrous α-NaHSO4 is formed with small amounts of NaHSO4·H2O. AFM measurements on NaCl (100) show the formation of two distinct types of NaHSO4 structures consistent in shape with α-NaHSO4 and β-NaHSO4. The β-NaHSO4 structures are mobile and move along the NaCl (110) plane until they encounter existing stationary α-NaHSO4 structures whereupon the two forms coalescence to form larger α-NaHSO4 structures. Gravimetry was used to determine the amount of HCl evolved upon exposure to aqueous H2SO4 solutions modeling atmospheric aerosols. At low H2SO4 concentrations, a large percentage of the HCl formed remains dissolved in the H2O. These results indicate that for conditions simulating relative humidities above 40%, the fraction of HCl released from this reaction may be as low as 0.40 ± 0.11.
