Chemicals That Smell Like Food: Glacial Acetic Acid

    I’m a scientist and foodie and there are a few chemicals in the lab that give off odors that remind me of food and there are reasons why. So, in this first edition of Chemicals That Smell Like Food, let’s talk about Glacial Acetic Acid. 

    Whenever someone uses this in the lab it takes me back to the famous vinegar fries I'd look forward to getting that at the local fair in my hometown. So why does Glacial Acetic acid smell like vinegar? Well, it is because vinegar is comprised of about 4-6% of acetic acid. The acid is a by-product of fermentation. The kind we use in the lab is the purest form, hence "Glacial" being in the title. Other commercial uses include the manufacture of vitamins, antibiotics, hormones, and organic chemicals, and as a food additive. 

Safety Notes: 

*Always used Glacial Acetic Acid under the hood.

*Wear protective clothing to protect your skin and eyes. 

*DO NOT deeply inhale this.
