FAQ
What is the CAS-no. and formula of Hydrochloric Acid?
Hydrochloric Acid is a single-component inorganic acid with the chemical formula HCl and CAS No. 7647-01-0.
What are the synonyms, physical, and chemical properties of Hydrochloric Acid?
Hydrochloric Acid is a colorless liquid free from suspended matter. Both ACS Reagent Grade and Semiconductor Grade typically contain 36.5–38.0% hydrogen chloride. The product has very low allowable impurity levels, including sulfates, sulfites, phosphates, heavy metals, and trace elements, with tighter impurity limits for Semiconductor Grade material.
What safety precautions should be taken when handling Hydrochloric Acid?
Avoid contact with skin, eyes, and clothing and do not breathe vapors or mists. Wear appropriate protective gloves, protective clothing, eye protection, and face protection. Wash thoroughly after handling and remove contaminated clothing before reuse. Seek immediate medical attention if exposure occurs.
What are the appropriate engineering controls for Hydrochloric Acid?
Use in well-ventilated areas with corrosion-resistant exhaust ventilation. Local exhaust ventilation is recommended to control acid vapors. Emergency eyewash stations and safety showers should be readily available in handling areas.
