WebA neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H + ions and OH – ions which form water. A neutralisation reaction is generally an acid-base neutralization reaction.
WebTherefore solutions of these substances conduct electricity very well. But acetic acid (K a = 1.76 x 10 -5) 1 and ammonia (K b = 1.78 x 10 -5) 2 only dissociate slightly in water. Therefore their solutions only conduct electricity weakly. Ammonia dissociates according to the equation: NH 3 ( aq) + H 2 O ( l) <=>.
