Product Details

Inorganic #9 in a dedicated acid cabinet. If one is not available, store in a Flinn Saf-Cube™. SPECIAL STORAGE TIP: Hydrochloric acid fumes a lot—particularly when warm. These fumes are responsible for most of the corrosion damage in your acid storage area. To solve this problem, store hydrochloric acid bottle(s) in a tightly sealed plastic bag. Be sure to label the outside of the plastic bag since acid fumes will soon destroy the bottle label. Spray the label on the bottle with Krylon® plastic spray (AP1559) if you wish to preserve it.
Shelf Life:
Good if stored safely.
Very strong chlorine
CAS No.:
Technical Note:
Incompatibility: Avoid storing hydrochloric acid anywhere in the vicinity of formaldehyde. A potent carcinogen, chloromethoxychloromethane, is formed when hydrochloric acid and formaldehyde react in air. This serious potential problem further emphasizes the need to store hydrochloric acid in a dedicated acid cabinet.
