Solution
We have to remember that the neutralization reaction is a reaction, always the reactants are an acid and a base, the formation of the product is always a salt and water, and it involves the combination of H+ and OH−ions to give water.
For example,
AB+CD→CB+AD
The above reaction is also a double displacement reaction.
Complete step by step answer:
Now we discuss the given option as one by one,
In option (i)the given compound is ammonium chloride which has the chemical formula ofNH4Cl. It is obtained from a neutralization chemical reaction as follows,
When ammonium hydroxide (chemical formula-NH4OH) act as a base and hydrogen chloride (chemical formula-HCl) act as an acid, they neutralize each other to give the products Ammonium chloride,NH4Cl, which is a salt and also gives water molecule.
NH4OH+HCl→NH4Cl+H2O
In the above chemical reaction, the positive ammonium ion (NH4+) from the base and the negative chloride ion (Cl−) from the acid to form the salt NH4Cl . And the negative hydroxide ion (OH−)from the base and the hydrogen ion (H+)from the acid to give water (H2O) .
So, from the above information the missing data is HCl, an acid.
In option (ii)
The given compound is copper sulphate (chemical formula is CuSO4). It is obtained from a neutralization chemical reaction as follows,
Cu(OH)2+H2SO4→CuSO4+H2O

Note:
Generally an acid-base neutralization reaction is also a neutralization reaction. If a solution is neutralized, then that salts are formed from equal weights of base and acid.
We have to remember that an acid is a substance which has sour taste and acid has the capacity to turn blue litmus to red. The acid has a tendency to be soluble in water and conduct electricity.
While the base is a substance which has bitter taste and which has the capacity to turn red litmus to blue.
