HAZARD ALERT: Corrosive to skin and tissue; moderate fire risk (flash
point: 39 °C); moderately toxic by ingestion and inhalation. LD50 3310 mg/kg. TLV
25 mg/m3.
Storage: Organic #1 inside a dedicated acid cabinet. Store away from nitric
acid. If acid cabinet is not available store in Flinn Saf-Cube™. Acetic acid crystallizes
at 16.6 °C. Room temperature is normally about 25 °C. So, a 10-degree
reduction from room temperature will cause the material to crystallize. Return
the substance to a warm environment and it will return to a liquid state. Such
a freezing/defrosting process does not alter the nature of the substance.
Disposal: #24a
Shelf Life: Indefinite if stored properly. Cap safety color code: Brown.
Soluble: Miscible with water, alcohol, glycerol and ether. Insoluble in carbon
disulfide.
Color and Odor: Colorless liquid with pungent vinegar odor.
CAS No. 64-19-7
Safety Purchase Suggestion: Buy and store only small quantities. Please
consider buying PVC (poly vinyl chloride)–coated acid bottle—Flinn Plas-Pak™.
* Acetic acid is exactly as described under catalog number A0006 but in
a PVC-coated bottle. In the event of breakage, acid and glass shards are
retained in a PVC outer envelope. The PVC-coated bottle is a safer package
for science teachers.
