Is an acid-base neutralization reaction exothermic or endothermic? . . .
Common exothermic reactions: a. Reactions of reactive metals with water or acids； b. Acid-base neutralization reaction ； c. Combustion reaction ； d. Most combination reactions ； e. Concentrated sulfuric acid, sodium hydroxide dissolved in water. Common endothermic reactions: a. Most decomposition reactions ； b. Reaction of ammonium chloride with barium hydroxide crystals at room temperature ； c. Reactions of carbon with water vapor and carbon dioxide at high temperatures ； d. Ammonium salts dissolve in water. Rule: a. Whether a reaction is endothermic or exothermic depends only on the reactants and products, not on the reaction pathway ； b. Conditions for complete combustion of fuel: an appropriate excess of air, and a sufficient contact area between the fuel and air ； c. Energy conservation
Exothermic reaction, a conclusion drawn from experiments in junior high school
The acid-base neutralization reaction, namely H+ + OH- = H2O, has a heat effect of 57.3 kJ/mol, with heat being released.
Acid-base neutralization is generally an exothermic reaction; of course, the amount of heat released varies depending on the acids and bases involved. Strong acids and strong bases release more heat, while weak acids and weak bases release less heat ! !
The neutralization of acids and bases is an exothermic reaction, which can generally be referred to as the heat of neutralization. The heat of this reaction can be found in relevant manuals, or it can be calculated based on the enthalpies of formation of the corresponding acids, bases, and salts.
Acid-base neutralization reactions are all exothermic reactions. The simplest way is to consult the reaction heat data for substances in chemical handbooks; a positive value indicates an exothermic reaction, while a negative value indicates an endothermic reaction.
Exothermic reactions – those that produce water are basically exothermic reactions!
Exothermic reactions; it’s just a matter of scale
It must be an exothermic reaction! ! !
