A carbon atom bound to three atoms

(two single bonds, one double

bond) is sp2 hybridized and forms

a flat triagonal or triangular

arrangement with 120° angles

between bonds. Notice that acetic

acid contains one sp2 carbon atom

and one sp3 carbon atom.

Carboxylic acids behave as acids because when they are dissolved in water they will deprotonate to form a carboxylate ion and the hydronium ionCarboxylic acids are weak

acids with dissociations of less than 5%

Carboxylic acids DO react with strong bases to form carboxylate salts

A process of neutralizationAcid protons are removed

by the –OH - to form H2O and carboxylate ion

Equilibrium shifts to the right with removal of H+

Carboxylic acids are prepared :by oxidizing primary

alcohols or aldehydes. from the oxidation of

ethanol, which produces ethanoic acid (acetic acid).

Current important uses

of acetic acid

Acetic Acid is used as an

ingredient in plastic,

vinegar, lacquers and is a

preservative itself.

Acetic acid is made by the process of fermenting various substances: starchy solutions, sugar solutions or wine with Acetobacter bacteria.

It would help future colonies produce a variety of lightweight instruments for daily use from plastic or keep food fresh for a long time by fermenting it. It’s very useful in space, considering there isn’t a

good climate to grow crops.

To produce acetic acid on a large scale, you would need to use: Filters, desalting machinery, evaporation machines and distillation equipment. It is a bit

expensive, but worth it. I think it should be the one to travel to space and help humans in their daily life.

Acetic acid can produce vinegar and is a fermenting substance itself. It can help future

colonies to keep their food

fresh and healthy for a long time without rotting.

Acetic acid is also an ingredient in plastic, which

is very useful in making different gadgets and tools.
