Question

Sodium acetate when dissolved in water undergoes-
A. acidic react ion
B. basic reaction
C. neutral reaction
D. hydrolysis reaction

Answer 1

Hint: A chemical reaction occurs when one or more compounds, known as reactants, are changed into one or more distinct substances, known as products. Chemical elements or compounds are examples of substances. The constituent atoms of the reactants are rearranged in a chemical reaction, resulting in the formation of various substances as products.

Complete answer:
Chemical formula for Sodium Acetate solution is $C{H_3}COONa$
When it react with water,
$C{H_3}COONa \to C{H_3}CO{O^ - } + N{a^ + }$
When an acid and a base are combined, the acid and base characteristics are neutralized, resulting in the formation of a salt. The acid's ${H^ + }$ cation mixes with the base's $O{H^ - }$ anion to generate water. A salt is a compound created by the cation of the base and the anion of the acid.
The word hydrolysis comes from the Greek words hydro, which means water, and lysis, which means to break or unbind. Water molecules are usually connected to two regions of a molecule during hydrolysis. The H+ ion will be given to one molecule of a chemical, while the OH- group will be given to the other. Polymers are broken down into monomers using the hydrolysis reaction.
When sodium acetate is dissolved in water, it is hydrolyzed. When a salt of a weak acid or weak base (or both) is dissolved in water, salt hydrolysis occurs. Water ionises into hydroxide anions and hydrogen cations on its own. In water, sodium acetate splits into sodium and acetate ions. The sodium ions react very little with the hydroxide ions, but the acetate ions form acetic acid when they mix with hydrogen ions.

So, the correct answer is “Option D”.

Note:
Sodium acetate is a water-soluble hygroscopic powder. Food, industry, concrete manufacturing, heating pads, and buffer solutions could all benefit from sodium acetate. When delivered intravenously, sodium acetate is a vital component as an electrolyte replenisher.
