Web25 Jul 2012 · Exothermic means that energy is released by the chemical reaction. In other words, energy is an output of the reaction, along with the reaction products. Endothermic means that energy is an *input* to the reaction. In other words, the reaction won't occur unless if you give energy to the reactants. WebThe slideshow describes an exothermic reaction between dilute sodium hydroxide and hydrochloric acid, and an endothermic reaction between sodium carbonate and ethanoic …
Heat of Neutralization: HCl(aq) + NaOH(aq) Chemdemos
Web30 Jan 2024 · For reactions involving acetic acid or ammonia, the measured enthalpy change of neutralization is a few kJ less exothermic than with strong acids and bases. For example, one source which gives the enthalpy change of neutralization of sodium hydroxide solution with HCl as -57.9 kJ mol -1: NaOH ( aq) + HCl ( aq) → Na + ( aq) + Cl − ( aq) + H2O WebAn exothermic process releases heat, causing the temperature of the immediate surroundings to rise.
