Question
Which of the following is a neutralisation reaction?
Options:
A .  NaOH(aq) + HCl(aq)→ NaCl(aq) + H2O(l)
B .  2HCl(aq) + 2Na(s) → 2NaCl(aq) + H2(g)
C .  Na2CO3(aq) + H2O(l) → 2NaOH(aq) + CO2(g)
D .  NH3(aq) + H2O(l) → NH4OH(aq)()
Answer: Option A
:
A
When an acid reacts with a base, it forms salt and water. This is called neutralisation reaction.
Here, only the reaction between hydrochloric acid with sodium hydroxide is a neutralisation reaction since it gives sodium chlorideand water as products. The reaction involved is given below:
HCl(aq)+NaOH(aq)NaCl(aq)+H2O(l)
