If you react an acid and a base together, eg. HCl + NaOH, the compounds will disassociate into ions, and then the H+ and OH- ions combine to produce water, and the other ions, eg. Cl- and Na+, will form a salt, eg. NaCl
neutralization in chemistry means the reaction of an acid with a base , in this process always a salt is produced and if base is alkali then water is another product but Lewis base forms only salt...
