Question

Ethanoic acid is also known as.
A) Citric acid.
B) Nitric acid.
C) Acetic acid.
D) Formic acid.

Answer 1

We know that acetic acid, efficiently named Ethanoic acid is a dry fluid natural compound with the chemical formula composed as$C{H_3}COOH$. At the point when undiluted, it is called glacial acetic acid. Vinegar is no under $4\%$ acidic corrosive by volume, making acidic corrosive the fundamental segment of vinegar separated from water.

Complete answer:
We have to remember that ethanoic acid is carboxylic acid and is usually called Acetic acid. It is somewhat heavier than water. Subsequent to adding $5 - 8\%$ of acidic corrosive water it becomes vinegar and is generally utilized as additives in pickles. Acetic corrosive is the second easiest carboxylic acid consisting of a methyl group appended to a carboxyl group.
Therefore, the option C is correct.
It is a significant substance reagent and modern compound, utilized basically in the creation of cellulose acetic acid derivation for photographic film, polyvinyl acetic acid derivation for wood paste, and engineered filaments and textures. In families, weakened acidic corrosive is frequently utilized in descaling operators.
We have to know that citric acid is an organic acid having the molecular formula of ${C_6}{H_8}{O_7}$. Therefore, the option A is incorrect.
We have to remember that the nitric acid is also known as aqua fortis and spirit of niter with the molecular formula of $HN{O_3}$. Therefore, option B is incorrect.
We have to know that the formic acid is also known as methanoic acid with the molecular formula of $HCOOH$. Therefore, the option D is incorrect.
Thus the correct option is C.

Note: Now we can discuss about the uses of acetic acid as,
-Ethanoic corrosive is broadly utilized in numerous enterprises.
-Monetarily it is utilized in the assembling of esters, vinegar, and numerous polymeric materials.
-Vinegar has appeared to diminish high groupings of glucose.
-Utilized as a specialist to lyse red platelets before white platelets are analyzed.
-Utilized as a dissolvable in the creation of camphor, climb and cooking fixing.
-Utilized as a stop shower for photographic emulsion improvement.
-Ranchers now and again splash acidic corrosive on domesticated animal’s silage to battle contagious and bacterial development.
