Neutralisation is the reaction between an acid and a base to form a salt and water.
The reaction of an aqueous hydrochloric acid solution with an aqueous sodium hydroxide solution is represented by the neutralization chemical equation
HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)+heat
The heat of neutralization is highest in HCl+NaOH

Heat of Neutralization
The heat of neutralization is the amount of heat evolved when one gram equivalent of an acid and a base react to form water and a salt.
Factors Affecting Heat of Neutralization
The heat of neutralization depends on the following factors:
1. The strength of the acid and base used.
2. The concentration of the acid and base used.
3. The temperature at which the reaction is carried out.
Answer Explanation
In the given options, the neutralization of sodium hydroxide by hydrochloric acid is the most exothermic reaction, and hence it has the highest heat of neutralization. This is due to the following reasons:
1. The strength of the acid and base used:
Sodium hydroxide is a strong base, and hydrochloric acid is a strong acid. The strength of the acid and base used affects the heat of neutralization. Strong acids and bases have a higher heat of neutralization compared to weak acids and bases.
2. The concentration of the acid and base used:
The heat of neutralization also depends on the concentration of the acid and base used. However, since the options do not mention the concentration of the acid and base, it can be assumed that the concentration is the same for all the options.
3. The temperature at which the reaction is carried out:
The heat of neutralization also depends on the temperature at which the reaction is carried out. However, since the options do not mention the temperature, it can be assumed that the reaction is carried out at the same temperature for all the options.
Therefore, based on the strength of the acid and base used, the neutralization of sodium hydroxide by hydrochloric acid is the most exothermic reaction, and hence it has the highest heat of neutralization.
