Question

Write the type of reaction:
Sodium hydroxide solution is treated with the acetic acid to form the sodium acetate and water.
a.) Combination reaction
b.) Neutralization reaction
c.) Decomposition reaction
d.) Displacement reaction

Answer 1

Hint: Sodium hydroxide is a base which is reacting with acid that is acetic acid and forms sodium acetate as the product which is salt along with the water. Try to analyze the reaction in which acid reacts with the base to produce salt and water and try to find out the name of the reaction.

Complete step by step answer:
Given that sodium hydroxide solution is treated with the acetic acid to form the sodium acetate and water. The reaction is as shown below
$\text{NaOH + C}{\text{H}}_3\text{COOH }\to \text{ C}{\text{H}}_3\text{COONa + }{\text{H}}_{\text{2}}\text{O}$

In the above reaction sodium hydroxide is a base and acetic acid is the acid. These acids and the base react with each other to produce sodium acetate which is nothing but salt and water is produced as the by-product. In this reaction the acid is neutralized with the base producing the salt and the reaction is known as the neutralization reaction.
So, the correct answer is “Option B”.

Note: The above reaction is also known as double displacement reaction. Because in the reaction both the reactants exchange their ions to give products and hence reaction is called as double displacement (two ions are displaced their position to form products).
