Webb1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2. Acid with values less than one are considered weak. WebbTherefore 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) <=>. NH 4+ ( aq) + OH - ( aq )
