13 Neutralization reaction examples: Detailed explanation

This research would provide the fundamental neutralization reaction examples to improve the knowledge about this type of reaction. It is important to know about neutralization reaction as it holds huge impact on regular lifestyle of human being.

The reaction between acid and base and formation of natural salts (pH level around 7) and water is called neutralization reaction. A broad range of Neutralization reaction example has been described through the following topics:

Neutralization reaction happens in strong acid and strong base

In a very basic context it can neutralization stands for the reactions which are reliable in giving out water and salts (neutral compounds).  Strong acids and strong bases do not differ from this concept. Two examples of the neutralization reaction between strong acids and strong bases are being discussed below:

Example 1: Simple formation of table salt that is NaCl is the most relevant example of neutralization between strong acid and strong base. The reaction between strong hydrochloric acid and strong sodium hydroxide gives out water and NaCl (Table salt).

Equation:

HCl + NaOH = NaCl + H2O

Example 2: Another example of divalent acids and bases represents the strength of neutralization reaction. The reaction between Nitric acid (strong acid) and Barium hydroxide (strong base) gives out Barium Nitrate and water.

Equation:

Ba(OH)2 + HNO3 = Ba(NO3)2 + H2O

Neutralization reaction happens in strong acid and weak base

Example 3: Ammonium nitrate salt which is quite stable in nature comes from the neutralization reaction between weak base gaseous ammonia (NH3) and strong nitric acid (HNO3).

Basically, the reaction happens in two stages. At first the ammonia reacts with the proton present in nitric acid and forms and ammonium ion. That ammonium ion then reacts with the produced nitrate ion and gives out the actual ammonium nitrate salt.

Equation:

NH3 + HNO3 = NH4NO3

However, this reaction shows exothermic properties. Ammonium nitrate is highly explosive in nature.

Neutralization reaction happens in weak acid and strong base

Example 4: Carbonic acid (H2CO3) is a well-known weak acid and when it reacts with strong base sodium hydroxide it gives out basic salt of sodium nitrate. Both the acid and base helps each other to get neutralised and produce new stable product.

Though the salt is basic (pH is 11), it is a useful neutral salt anyway.

Equation:

H2CO3 + 2NaOH = Na2CO3 + 2H2O

Example 5: Another effective example of neutralization reaction takes place between weak acid and strong base is when acetic acid reacts with sodium hydroxide gives our sodium acetate salt and water.

Unbalanced Equation:

CH3COOH + NaOH = CH3COONa + H2O

Other than these the Strontium fluoride also comes from the reaction between highly corrosive Hydrofluoric acid and strong base strontium hydroxide (Sr(OH)2).

Neutralization reaction happens in weak acid and weak base

Example 6: Acetic acid (weak acid) and calcium carbonate (weak base) reacts with each other and forms acetate and water. In this reaction release of CO2 gas is also noticed as exception.

Not exactly exception, it can be noticed that when carbonate bases reacts with acid they give out Carbon Dioxide gases along with water and basic salts.

Equation:

CH3COOH + CaCO3 = CH3COOCa + H2O + CO2

Neutralization reaction in agriculture

Example 7: In the case of farming it is very important to treat the soil with proper chemical elements. The soil treatment process is noticed to be followed by the application of principles of neutralization reaction.

The cultivation of crops should be carried out in the soil which is neither too basic nor too acidic. For making the soil neutral tis is treated with bases like lime (calcium hydroxide).  In the case of reducing acidic nature of the soils organic compounds are mixed with the soils and it does enhance the neutral strength of soils anyway.

As an example magnesium carbonate neutralises the acidic soils and brings forth high-quality nutrients to the plants.

Neutralization reaction examples in pharmaceutical context

Example 8: On the basis of pharmaceutical context it has been identified that the buffer solutions are highly encouraging factors in chemistry. Buffers can be three types’ acidic buffer, basic buffer and neutral buffers.

All the buffers contain acid and bases both and the pH level of buffer solutions are always constant. These solutions re influentially made by using the principle of neutralization reaction. It can be said that these solutions are great example of neutralization reaction product.

Ammonium acetate is a great example of buffer which is formed by proceeding as neutralization reaction example.

Neutralization reaction in daily life

Example 9: In regular life of human being brushing tooth is the first job for which people do after opening eyes in the morning. The basic toothpaste that has been used by every individual is great and appropriate example of neutralisation.

The acids formed by the food particles inside the gaps between teeth are decayed by the toothpaste (combination of alkaline or basic compounds).  It reduces the possibility of tooth decay by keeping the teeth neutralised.

Example 10: The mildly alkaline substance shampoo is used in daily life to wash hairs. The impact of a shampoo on the hair is noticed to follow the neutralization reaction.

Conditioner is used after shampoo to neutralise the mild alkaline effect of shampoo in the hair. It restores the neutralised moist nature in the hair and makes it healthy.

Neutralization reaction in industrial waste treatment

Example 11: the industrial waste formation is very common matter in this recent era. Most of the industrial wastes are acidic and toxic by nature. Therefore, treating those with basic compounds proceeds through neutralization.

It reduces the possibility of damage of nature by the acidic wastes through the proper implementation of neutralization reaction.

Neutralization reaction in Rubber industry

Example 12: In the case of rubber production it is very important to prevent the coagulation of latex. This prevention are noticed to be dine with the application of neutralization reaction where lactic acid are neutralised by the ammonia solution (NH4OH).

Neutralization reaction in human body

Example 13: Antacids are effective example of neutralization reaction. When a person suffers from acidity antacids are recommended to intake. Antacids help to neutralise the acids forms inside the stomach by the basic composition it contains such as magnesium hydroxide or aluminium hydroxide and others.

Example 14: When bees sing or bite at any body part it the toxicity spreads into human body in the form of formic acid. It is neutralised by the application bases like baking soda or baking powder. It effectively helps to cut off the possibility of inflammation or infection. Basically the base applied proceeds neutralization reaction to reduce toxic effect of the formic acid.

Neutralization reaction takes place as an example of exothermic reaction. It is influenced by the release of extra heat in the nature. Besides neutralization reactions are also the different side of thoughts of double displacement reaction.

Frequently Asked Questions (FAQs)

Question 1: What is the basic concept of neutralization reaction?

Answer: According to the basic concept of Neutralization reaction, acids and bases react with each other and give out salt and water. The salts appear as stable compound in nature.

Question 2: Does neutralization reaction occur as exothermic reaction? If yes, explain why?

Answer: Yes, Neutralization reactions occur as exothermic reaction. These reactions release a certain heat which is the foremost principle of exothermic reaction.

Question 3: How does Double Displacement reaction take place in neutralization reaction?

Answer:  Double Displacement reaction takes place in neutralization reactions when an acid release its cations and the base releases its OH ions, salt is formed by adopting the cations and water molecules form by adopting OHions.

Question 4: Give an example of neutralization reaction where Carbon Dioxide gas appears as product simultaneously with water and salt.

Answer: Acid-carbonate base neutralization reactions produce CO2 along with salt and water, such as,

4HCL + 2Na2CO3 = 4NaCl + 2H2O + 2CO2

Question 5: What is Table salt? How it is formed?

Answer: NaCl is called generally table salt which we put in food in daily life.

It is formed by neutralization reaction between strong acid and strong base
