Hydrochloric Acid and Dilute Hydrochloric Acid
CAS Number: 7647-01-0
Molecular Formula: HCl
Molecular Weight: 36.46
Hydrochloric Acid and Dilute Hydrochloric Acid
Hydrochloric acid (CAS 7647-01-0) is a strong, highly corrosive acid with the formula HCl. It is a water-based solution of hydrogen chloride gas, commonly known as muriatic acid. It is clear, colorless, and has a strong, sharp smell.
Hydrochloric Acid USP NF Grade:
HCl --- 36.46 --- CAS 7647-01-0.
Hydrochloric Acid contains not less than 36.5 percent and not more than 38.0 percent, by weight, of HCl.
Packaging and storage: Preserve in tight containers.
Identification: It responds to the tests for Chloride.
Residue on ignition: To 20 mL add 2 drops of sulfuric acid, evaporate to dryness, and ignite: not more than 2 mg of residue remains (about 0.008%).
Bromide or iodide, Free bromine or chlorine, Sulfate, and Sulfite: To pass the tests.
Heavy metals: Evaporate 3.4 mL (4 g) on a steam bath to dryness, add 2 mL of 1 N acetic acid to the residue, then dilute with water to 25 mL: the limit is 5 ppm.
Hydrochloric Acid FCC Food Grade:
HCl --- Formula weight 36.46
INS: 507 CAS 7647-01-0
DESCRIPTION
Hydrochloric Acid occurs as a clear, colorless or slightly yellow, corrosive liquid. It is a water solution of hydrogen chloride of varied concentrations. It is miscible with water and with alcohol. Concentrations of Hydrochloric Acid are expressed in percent by weight or may be expressed in degrees Baume´ from which percents of Hydrochloric Acid and specific gravities may readily be derived. Concentrated Hydrochloric Acid fume in moist air, lose hydrogen chloride, and create a corrosive atmosphere. Because of these characteristics, observe suitable precautions during sampling and analysis to prevent losses.
Function: Acidifier.
REQUIREMENTS
Labeling: Indicate the content, by weight, of Hydrochloric Acid (HCl). Alternatively, indicate the range of Hydrochloric Acid content, the range of degrees Baume and/or the specific gravity range.
Identification: A sample gives positive tests for Chloride.
Assay: Not less than 97.0% and not more than 103.0% of the labeled amount of HCl, or within the range specified on the label.
Color: Passes test.
Iron: Not more than 5 mg/kg.
Lead: Not more than 1 mg/kg.
Nonvolatile Residue: Not more than 0.5%.
Organic Compounds: Total Organic Compounds (Non-Fluorine-Containing) -Not more than 5 mg/kg, including Benzene Not more than 0.05 mg/kg. and Fluorinated Organic Compounds (total) Not more than 0.0025%.
Oxidizing Substances (as Cl2): Not more than 0.003%.
Reducing Substances (as SO3): Not more than 0.007%.
Specific Gravity: Within the range specified or implied by the vendor.
Sulfate: Not more than 0.5%.
