Produktdetaljer

Eddikesyre, also called acetic acid, er en organisk forbindelse, is an organic monic acid, the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.6 ° C (62 ° F). After solidification, it becomes a colorless crystal, which is weakly acidic and corrosive in its aqueous solution. It is strongly corrosive to metals, and the steam is irritating to the eyes and nose.
