Question

The reaction between an acid and base to give salt and water is known as .
A.Displacement reaction
B.Neutralization reaction
C.Decomposition reaction
D.Double displacement reaction

Answer 1

Hint: When an acid and base reacts with each other they form salt and water. These reactions are generally used to determine the PH of solution. Basically salts consist of cation and anion ex- $N{{a}^{+}},C{{l}^{-}}$are cation and anion respectively of sodium chloride.

Complete step by step solution:
Salts are obtained by the neutralization reaction between the acids and bases ex-
Let us take $HCl\, and\,NaOH $ where $HCl$ is an acid and $NaOH$ is base
When $HCl\, and \,NaOH$ react they produce water and $NaCl$
$HCl + NaOH\to NaCl+{{H}_{2}}O$
Sodium chloride and water are the products obtained on reaction of hydrochloric acid and sodium hydroxide base. The neutralization reaction can take place between strong acid, strong base or weak acid, strong base or strong acid, weak base, etc.

So, Option ‘B’ is the correct answer.

Note: Note that salts are a result of acid base reaction. Further the salts are classified into the various categories as Acidic acid, basic salt, double salts, complex salt, and simple salts. The table salt which we used in our day to day life is $NaCl$. Displacement reaction is the one in which atoms of a molecule or compounds are replaced by atoms of other molecules or compounds. In double decomposition reaction, mainly two ions are replaced with one another. Like cation is replaced by another cation and anion is replaced by another anion. In decomposition reactions, compounds decompose into two or more simpler compounds.
