What is the enthalpy (heat) of neutralization? Neutralisation is the reaction between an acid and a base to form a salt and water. Some examples of neutralisation reaction are as follows.During neutralisation reaction, hydrogen ions from acid react with hydroxide ions from alkali to form water. H+(aq) + OH-(aq) → H2O(aq) Since water is formed during … [Read more...] about What is the enthalpy of neutralization?
