Why neutralisation reaction is an exothermic reaction?
Answers
Answer:
SInce strong acids and strong bases are completely dissociated in solution, no formal bonds are being broken. The formation of two very strong covalent bonds between hydrogen and the hydroxide ion is responsible for the neutralization reaction's exothermic character.
Due to enthalpy change by the formation of water along with salt.No matter which acid or base has been taken.
Due to enthalpy change by the formation of water along with salt.No matter which acid or base has been taken.When strong acid is taken it dissociates into H+ ions strongly which reacts with strong base's OH- ion during which there is strong enthalpy change due to high temp. N it evolves lot of heat.Same happens with any acid or base.With weak acid or weak base only less amount of H+ or OH- dissociates so less heat is produced.
