Question

What is the equation of a neutralization reaction between sodium hydroxide and hydrochloric acid?

Answer 1

In this question, we will know what the reactants are. Example: In this, We know that the reactants are hydrochloric acid and sodium hydroxide and they both react with each other. The chemical formula of Sodium hydroxide is NaOH and the chemical formula of hydrochloric acid is HCl.

Complete answer:
Now, look at the reaction and figure out which one of them is a strong acid and which one is a strong base if it is not mentioned in the question. If you fail to do so, you can always look at a table of strong acids and strong bases in your chemistry book.
In this particular question, The strong acid is hydrochloric acid and the strong base is sodium hydroxide. Now, we have to see the kind of reaction happening in the neutralization equation. Mostly. The double displacement reaction is the reaction. This reaction is defined as when one of the elements or compounds of one of the reactants combines with an element or compound of the other reactant.
Example- When HCl is reacting with NaOH, Then H of the HCl gets bonded with OH in the NaOH, and Cl combines with the Na.
The neutralization reaction of Sodium hydroxide and Hydrochloric acid gives Sodium chloride and water.
$HCl+NaOH\to NaCl+{{H}_{2}}O$

Note:
Balancing the chemical equation is necessary. To balance the neutralization reaction includes that there should be an equal number of moles of each element on both sides of the chemical reaction. In the above neutralization equation, it is already balanced as two moles of H are there on both sides, one mole of Cl on both sides, one mole of Na on both sides, and one mole of O on both sides.
