Enthalpy changes of neutralisation are always negative - heat is given out when an acid and and alkali react. Very good explanation and examples, excellent. The carbon dioxide forms a weak acid (carbonic acid, \(\ce{H_2CO_3}\)) in solution which serves to bring the alkaline pH down to something closer to neutral. Stage 4. Reactions where at least one of the components is weak do not generally result in a neutral solution. Required fields are marked *, Relation Between the Strength of Reactants and Resultant pH. Neutralization reactions are used in industry when there is leakage of an acid or a base, since each in its concentrated state is a corrosive substance, dangerous for a human being to have contact with it.
