Neutralisation reaction is a chemical change. Justify this statement with the help of an example.
A neutralization reaction is one where an acid and a base react to form water and salt.
It involves the combination of H+ ions and OH- ions to generate water.
When a solution is neutralized, it means that salts are formed from equal weights of acid and base.The pH of any neutralized solution depends on the acid strength of the reactants
Acid + Base --> Salt + Water
Therefore salt is a combination of a metal ion and a non-metal ion
Example- HCl + NaOH --> H2O + NaCl
(Acid) + (Base) (H+OH-) + (Sodium Chloride or Salt)
Since, this reaction is Irreversible and Permanent, as a new product is formed at the end of the reaction, it is a Chemical change.
[Extra information: The above reaction is also known as a double displacement reaction. A double displacement reaction is one in which there is an exchange of ions between the reactants.]
