Answer 1

Hint- In order to deal with this question we will see which compound and gas will be formed after this reaction and further we will write the reaction to get the answer we will further see some uses of ethanoic acid and sodium ethanoate.

Complete step-by-step answer:
The inorganic compound with the formula \[N{a_2}C{O_3}\] and its numerous hydrates is sodium carbonate, \[N{a_2}C{O_3}\] , (also known as washing soda, soda ash, and soda crystals). Both types are salts which are white and water soluble. Both sources have a heavy alkaline flavor, and have mildly alkaline water solutions.
Ethanoic acid \[C{H_3}COOH\] belongs to the carboxylic acid group, which is generally referred to as acetic acid. At a density of \[1.05{\text{ }}g/c{m^3}\] it's marginally heavier than water. It is vinegar after applying $5 - 8\% $ of acetic acid in water and is often used in pickles as preservatives. The specific name for ethanoic acid is acetic acid
If we dump a dilute ethanoic acid onto a white sodium carbonate an instant fizzing happens as carbon dioxide is created and we end up with a colorless sodium ethanoate solution.
Here is the reaction of sodium carbonate with ethanoic acid :
\[2C{H_3}COOH + N{a_2}C{O_3} \to 2C{H_3}COONa + C{O_2} + {H_2}O\]
Ethanoic acid reacts with sodium carbonate to create ethanoate with salt, oxygen and carbon dioxide.
Hence the reaction of sodium carbonate and ethanoic acid is:
\[2C{H_3}COOH + N{a_2}C{O_3} \to 2C{H_3}COONa + C{O_2} + {H_2}O\]
So, the correct answer is option A.

Note- Sodium ethanoate is most commonly labeled sodium acetate. For the garment industry, sodium acetate is used to neutralize excess sources of sulfuric acid, and also as a photo resist using aniline dyes. This is also a pickling agent in chrome tanning, and aids in the manufacture of synthetic rubber to resist chloroprene vulcanization. Ethanoic or acetic acid is used in the manufacturing of colorings, pigments and oils for paint and painting. This is used in tissue printing. It is an essential component of wood glue and other sealants. Acetic acid also acts as a solution for washing and degreasing.
