Neutralization reaction is the reaction in which an acid reacts with the base to form salt and water after losing all the properties of both acid and base. They are always exothermic in nature as they produce the same amount of heat during the reaction.
HX (Acid) + BOH (Base) → BX (Salt) + H2O (Water)
In this reaction, H+ ion of the acid combines with the OH- ion of the base to give water.
NaOH + HNO3 → NaNo3 + H2O
Ca(OH)2 + 2HCl → CaCl2 + 2H2O
