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.
