The term amphoteric describes a substance that can act as both an acid and a base.
+molecule size +steepness of the concentration gradient +temperature + steepness of the electric gradient +steepness
I would say is because of the Boron from O?
Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution. Electrical conductivity of the compound in liquid form
