About Acetic acid

Acetic acid which is also known as Ethanoic acid is a colorless organic acid with chemicals formula C2H4O2 is liquid with strong and distinctive pungent and sour smell. Acetic acid got its name from a word “Acetum”, which is a Latin word for vinegar. Because of its presence in vinegar, it’s most well known, as the pungent and sour smell is because of acetic acid in vinegar.

 

Characteristics of acetic acid

  • Acetic acid is a weak acid.
  • Glacial Ethanoic acid is very much corrosive to metals.
  • Boiling point: 118.1 degree Celsius.
  • Melting point: 16.6 degree Celsius.
  • Acetic acid is miscible with water.
  • Acidity: 4.76 pKa, basicity 9.24 pKb, and viscosity 1.22 mPa s.
  • At STP it has the liquid state.
  • Sour in taste and have a pungent smell.
  • Freezes in its purest form. That is why it is also known as glacial acetic acid.

 

Ph and molarity of Acetic acid:

Ph of acids is dependent upon molarity and normality of the acid.

So, for 1.0 M or for 1N of acetic acid its pH value will be around 2.4.

Molarity and Normality of Acetic acid are 17.4.

Common Uses of Acetic acid:

Acetic acid is a chemical reagent is widely used for chemical compounds production.

  • The widespread use of acetic acid is in the Vinyl Acetate Monomer production, followed by ester and acetic anhydride production.

  • Acetic acid is used as a solvent mainly as a solvent for inks, paints, and coatings.

  • Acetic acid is used as a coagulant in manufacturing rubber and is also used in manufacturing many dyestuffs and perfumes.

  • Food industry: Used a table vinegar and as a preservative.

  • Medical industry: Acetic acid injection is used to treat cancer and is also used in antiseptic creams. It is also used in the treatment of otitis externa.

 

How acetic acid is made or production of acetic acid:

Acetic/Ethanoic acid is manufactured in industries through synthetically fermentation and bacterial fermentation. Around 75% of acetic acid which is made for use in chemical industries is made through methanol carbonylation which is a process in which carbon monoxide along with methanol reacts to produce acetic acid. Iodomethane is involved as an intermediate in this process. This process appears in three steps:

CH3OH + HI → CH3I + H2O
CH3I + CO → CH3COI
CH3COI + H2O → CH3COOH + HI

Hazards and safety?

Hazards:

  • Health hazard: Acetic acid is corrosive for skin and therefore should be handled with care. Acetic acid causes skin burns, tissue destruction or eye damage when it comes with contact to eyes or skin. Inhalation of Acetic acid also causes injury or can lead to death in case of large amount inhaled.

  • Fire hazard: Acetic acid is a combustible element so it may burn and form explosives materials with air.

Safety:

  • Acetic acid should be stored in a clean well-ventilated area and in a tightly sealed container.

  • Acetic acid should be kept away from heat and sources of heat.

  • Water should not be added to this chemical.

  • Following protective gears should be worn when handling acetic acid: Gloves, Splash Goggles, Synthetic apron.

  • It should be ensured that there are nearby eye-wash stations.
