What is the use of acetic acid?

Are you looking for a versatile acid that can grace your kitchen, clean stains in the laundry, and help fight off infections? Look no further than acetic acid! This puny-looking compound packs a powerful punch when it comes to its numerous uses. Let’s dive into the world of acetic acid and be prepared to have your mind blown!

What is Acetic Acid?

Acetic acid is an organic chemical compound with the general formula CH3COOH or C2H4O2. It is also known as ethanoic acid, vinegar acid, or methane carboxylic acid (but let’s stick with acetic for now) (1). Acetic has a pungent smell that may remind you of sour wine or vinegar; but bear in mind not always at desirable levels.

Acid-base reactions create it by mixing ethanol and oxygen while keeping them away from light – sound scientific right? It can even produce synergy alongside other acids like α Hydroxy acids found commonly in skincare products along side Glycolic or Lactic/ Mandelic/Malic depending on skin type and use.

When fully concentrated it freezes just below room temperature much like some anxious humans seeing their tax forms before deadline day approaching. When diluted however (always dilute) , household white vinegar mostly contains 5% – 8% of this gem by mass where food-grade variety reaches upto 20%.

Magic Molecules: Chemical Properties

Let’s get molecular! As we previously learned, acetic seems innocuous enough–just another organic molecule based on good ol’ carbon (C), hydrogen (H), and oxygen(O). But under its bland exterior hides several interesting secrets :

Double Bond Fun

What makes this “acid” different from sulphuric/HCl/phosphoric/gastric/ascorbic(acidity difference) is the presence of carboxyl group a carbon double bonded to an oxygen COOH which gives it its acidity properties (2). Random Fact: Citric acid in various citrus fruits have three -COOH groups coupled with citrate salts making up roughly 80% of energy production by our body starting from Acetyl Co A.

Hydrophillic-Phobic Love Story

Due to presence of electronegative oxygens on either end they create a polar molecule(separate charges i.e hydrophilic) that can interact with water- remember how oil doesn’t mix well? Chemistry begs to differ as non-polar bonds avoiding water are inherently stronger than weak fraternizations seen in acetic merrier with H20 (hydrophobic).

The Little Monster’s Superpowers: Versatile Uses!

And now, for what you’ve been waiting for—how we mere mortals use this fascinating chemical! Let’s see:

Recipe Rockstars and Master Chefs unite using Acetic

Acidified compounds elevate taste buds sensations(i.e Sourness); who won’t recognize vinegary aroma wafting through Crispy Fried Chicken or pickle brine filled jars at local diner served as condiments (the Russian Dill Pickle canned version is my favorite; I digress)?

It also serves another purpose : preservation.
Back in older days before refrigeration was common, natural vinegar after fermentation aside from great sour taste prevented microbial proliferation extending edibility longevity(3). With time researchers went ahead and added cellulose acetate butyrate(CAB) derived propionate esters primarily gaining popularity as antimicrobial agents used directly over food items like cheese,& dairy products keeping them safe for consumption just X day(s) more.

Want even more culinary based fun? Vinegar contains acetic acid which provides necessary pH needed during pickling – crucial when considering texture alterations while preserving food as Sodium benzoate or Potassium sorbate are acid pH dependent.

Cleaning Genius within it

You might be thinking vinegar for cleaning? You betcha! Vinegar mainly used is usually 5% acetic albeit can increase on requirements if targeting tougher stains never use >30%(>10-20% industry grades) (4). Use them to clean windows, mirrors, hardwood floors and much more with added benefit of being environmentally friendly too!

It not only cuts grease like a hot knife through butter but also helps removes dirt and grime in bathrooms after reacting(at times even dissolving)certain limestone deposits minerals by forming chelates(complexes i.e insoluble soap residues). With sustainable approach garnering attention nowadays, no wonder you’ll see SmartClean products ready grabbing the shelves – brownie points for their all-natural ingredients rite?

Pimples and Wounds Be Gone

Who knew acne and wounds could have such fancy chemistry behind em?
For example: Acne-prone skin with sebum/oil control issues are increasingly resorting towards naturally derived OTC topical solution containing glycolic/lactic acid along side Salicylic acid which extracts impurities from pores(but sparingly due to burning nature ) (7).

Unlike Higher purity concentrations used in lab settings(98%-99%), Concentrated solutions may result in irritation causing redness due to keratosis(i.e accumulation of dead skin cells/hyperkeratinisation) or over exfoliation, let’s stick instead with milder variants found mostly that balance efficacy without irritation concerns while maintaining barrier function which include Pyruvic/Gluconolactone amongst others pairable alongside colloidal silver/blue light therapy(11) for maximum output.(aforementioned names might make your tongue twisted; give ye ol’ dermatologist lookup)

Wounds sustain injuries when physical damages affects our immune system primarily platelets (thrombocytes) initiating the wound healing response. Acetic acid helps decrease pathogenic infiltration by affecting cell membrane lysis outcompeting bacteria for surface attachment via H bonding interactions further promoting wound closure(8).

Further More Other Miscellaneous Uses

  • In drug formulation industry, it’s utilized as intermediate manufacturing of antibiotics(penicillin,Gantrisin), painkillers, Vitamins processing(Pantothenate supplement)(9) (now whose complaining bout intake of the Salty Oats broth)

  • Also used when directly applied frozen tissue specimens replacing formalin thus proving useful in healthcare pathology labs (10)

  • Production agent involved in multiple usage scenarios like producing HDPE ethylene chain derived plastic polymer or application through electroplating(9); who knew people could be so creative and versatile with its properties?

Conclusion

Now that you’re familiarized with acetic acid—not to mention how obnoxiously witty I am—you can appreciate just how handy this little molecule truly is! From pickling cucumbers to cleaning windows for a great view outside while enjoying your only pot roast slathered in balsamic vinegar(acidic properties needed here too folks!) , there’s always an opportunity to harness yourself ’s unique abilities.
