Question

A base reacts with an acid to form salt and water. This reaction is called:
A) oxidation reaction
B) neutralization reaction
C) reduction reaction
D) ionization reaction

Answer 1

Hint: We know that the acid and base react with each other to form salt and water. And here salt and water are also known as a neutralized solution. We know that the pH of salt and water depends on the strength of acid and base.

Complete step by step answer:
Acids are known to turn blue litmus paper into red and liberate hydrogen gas on reacting with active metals.
Bases are known to turn red litmus paper into blue, baste bitter and soapy.
And pH of salt and water depends on the strength of acids and base used.
Let us see the example of neutralization reaction:
\[HCl + NaOH \to NaCl + {H_2}O\]
Here, \[HCl\] = Acid
\[NaOH\] = Base
\[NaCl\] = Salt
\[{H_2}O\] = water

Therefore, we can conclude that the correct answer to this question is option B.

Additional information:
Let us discuss the Arrhenius concept of acid and base:
According to the Arrhenius concept, an acid is a compound that gives free hydrogen ion when dissolved in water. Example \[HCl\] .
And the base is a compound that gives free hydroxyl ion when dissolved in water. Example \[NaOH\] .
Now let us discuss the Lowry-Bronsted concept of acid and base:
According to this concept, acid is a proton donor species. Example \[HCl\] .
And the base is the proton acceptor species. Example \[N{H_3}\] .
Now let us discuss the Lewis concept of acid and base:
According to this concept, acid is a substance that can accept a pair of electrons. Example \[B{H_3}\]
And the base is a substance that can donate the pair of electrons. Example \[N{H_3}\] .

Note: We know that in the acid-base reaction oxidation state of elements in the reactant and product does not change so oxidation reaction and reduction reaction is not possible. The acid-base reaction cannot be termed as ionization reaction because the ions formed here reacts to give neutral product molecule.
