Answer the following question as given below:----
Solution. When an acid is mixed with a base, both substances neutralize each other’s effect. The reaction between an acid and a base is known as a neutralization reaction. In a neutralization reaction, salt and water are obtained as products. Also, energy is evolved during the process. The general equation for the neutralization reaction is represented as:
Acid + Base → Salt + Water
1. Neutral salt: Salt that is formed when a strong acid reacts with a strong base. These salts are neutral in nature and their pH value is equal to 7.
Example: Sodium chloride
Sodium chloride (NaCl) is formed after the reaction between hydrochloric acid (a strong acid) and sodium hydroxide (a strong base).
2. Acidic salt: Salt that is formed when a strong acid reacts with a weak base. These salts are acidic in nature and their pH value is lower than 7.
Example: Ammonium chloride
Ammonium chloride is formed after a reaction between hydrochloric acid (a strong acid) and ammonium hydroxide (a weak base).
3. Basic Salt: Salt that is formed when a strong acid reacts with a weak base. These salts are basic in nature and their pH value is more than 7.
Example: Sodium carbonate
Sodium carbonate is formed after the reaction between sodium hydroxide (a strong base) and carbonic acid (a weak base).
- Neutral salt: The pH value of a neutral salt is almost equal to 7.
- Acidic salt: The pH value of an acidic salt is less than 7.
- Basic salt: The pH value of a basic salt is more than 7.
