Neutralization reaction is a reaction in which an acid is react with a base to form water and salt.
Hello reders, today i m going to explain about neutralization reaction, acid base neutralization reaction, heat of neutralization reaction and more.
Now, lets get started;
What is neutralization reaction?
Neutralization reaction is a chemical reaction process in which acid (HCl) and base (alkali, nacl) reacte together to form water and salt as a product. it is called acid base neutralization reaction. It is combination of H+ ions and OH+ ions which they form water and salt as a product.
Neutralization reaction
In case of neutralization process , acid(HCl) react with base(Nacl) to give water (H2O) and salt (Nacl).
For example;
Acid + base – salt + water
HCl + NaOH = NaCl + H2O
Where,
- Acid – HCl
- Base (alkali) – NaOH (sodium hydroxide)
- Water – H2O
- Salt – Nacl (sodium chloride)
Now;
Acid + base = water + salt
It mean,
HCl + NaOH = H2O + NaCl
Acid base neutralization reaction
You know that hydrochloric acid and sulfuric acid is a strong acid,
for examples,
Strong acid – HCl (hydrochloric acid)
Strong acid – H2SO4 (sulfuric acid).
similarly ;
Base = NaOH (sodium hydroxide) where base = alkali.
And Nacl – (sodium chloride) – salt.
When strong acids such as, HCl or H2SO4 is react with NaOH (sodium chloride = base) then it produce salt (Nacl) and water (H2O).
- HCl + NaOH = NaCl + H2O
- H2SO4 + 2NaOH = Na2so4 + 2H2O
h2so4 naoh
You know that, It is also a acid-base reaction.
H2SO4 (aq)+2NaOH (aq) – Na2SO4(aq) + l) (2H2O
where,
H2SO4 – sulphuric acid – (Acid)
Sulphuric acid is Colourless and viscous liquid with miscible with water at all concentration.
NaOH – sodium hydroxide – (base)
sodium hydroxide is also called caustic soda. it is a white crystalline solid. it is used for chlorine production.
Product is,
Na2SO4 – sodium sulphate
Sodium sulphate is a inorganic compound, it is white solids. it is highly soluble in water.
2H2O – water
the chemical name of water is H2O. It consist two hydrogen atoms and one oxygen atom. these element bound to form water.
Neutralization reaction equation
Neutralization equations is,
Acid + base > salt + water
HCl + NaOH > NaCl + H2O
The reaction between an acid (HCl) and a base (Na0H) to create and ions compound such as salt (NaCl) and water (H2O).
Neutralization reaction example
You know that creation of both salt and water by neutralization.
Where, NaCl = sodium hydroxide = Common salt
HCl + NaOH = NaCl + H2O
You can see both salt and water is produce by neutralization.
So,
HCl = strong acid = hydrochloric acid
NaOH = (alkali) = sodium hydroxide is main example of neutralization reaction.
Heat of neutralization
The heat of neutralization is defined as the quantity of heat is apply when one equivalent of an acid (HCl) and one quivalent of a base (NaOH) undergo a neutralization process to form water (H2O) and a salt (NaCl).
Similarly;
The heat of neutralization of a base amount of heat apply when 1 gram equivalent of the base is completely neutralized by a strong acid in a diliute solution.
HA + BOH > AB + H2O + 57.3 kj
Questions and answers
1. What two substances form from acid base neutralization?
Two substance form from acid base neutralization is,
- Water (H2O)
- Salt (NaCl)
Acid base neutralization reaction is,
HCl + NaOH 》 H2O + NaCl
Acid + base 》 water + salt
2. What is neutralization reaction give one example?
The best example of neutralization process is, hydrochloric acid (HCl). this is called a strong acid. In neutralization process ,when acid H+ are react with base OH- to form HOH or H2O (water).
In other word, it is combination hydrogen ions and hydroxyl ions to form water or HOH or H2O.
3. How strong are acid or base solution?
You know that, water or other solution have pH is 7. If pH is less then 7 then it indicate acidic and if pH is more then 7 (PH) it indicate basic.
