NITRE CAKE - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | sodium bisulfate, also known as sodium acid sulfate, is an inorganic compound with the chemical formula of NaHSO4 and white monoclinic crystals, it is hygroscopic, the aqueous solution is acidic, and the pH of 0.1mol/L sodium hydrogen sulfate solution is about 1.4. |
| Application | The application of sodium bisulfate is as follows: 1. Used as a flux and disinfectant, and for the preparation of sulfate and sodium alum. 2. Used as mineral decomposition flux, acid dye dyeing agent and preparation of sulfate and sodium vanadium, also used in the manufacture of toilet cleaner, deodorant, disinfectant. 3. Determination of bromine, iodine, copper and titanium dioxide. Mineral analysis. Household Cleaner (45% solution), extraction of metallic silver; Reduce the alkalinity of swimming pool water; Pet food. |
| preparation | sodium hydroxide and sulfuric acid are mixed in an amount of substances such as sodium hydroxide and sulfuric acid to obtain sodium hydrogen sulfate and water. NaOH H2SO4 → NaHSO4 H2O sodium chloride (salt) and sulfuric acid can react at high temperature to produce sodium bisulfate and hydrogen chloride gas. NaCl H2SO4→ NaHSO4 HCl |
| identification test | According to IT 29, sulfate identification test was positive. |
| content analysis | accurately weigh about 5g of sample, dissolve in about TS-167 of water, add several drops of phenolphthalein test solution (), titration with 1mol/L sodium hydroxide. Per mL of 1mol/L sodium hydroxide corresponds to sulfuric acid (H2SO4)49.04mg or sodium hydrogen sulfate (NaHSO4)120.06mg. |
| usage limit | GB 2760-2001: water preparation, 50mg/kg (13.7mg/kg in terms of sodium). |
| Use | used as analytical reagent and melting agent used as mineral decomposition flux, disinfectant, dyeing aids and preparation of sodium sulfate and sodium alum, etc. reagents for analysis and flux |
| category | corrosive article |
| flammability hazard characteristics | non-combustible; Toxic sulfur oxide and sodium oxide smoke emitted by decomposition in fire scene |
| storage and transportation characteristics | warehouse ventilation and low temperature drying |
