FE23Electrolytes—Ionic Solutions1.The acids HNO3, HClO4(perchloric acid), HCl, HBr, HI, and H2SO4are strongelectrolytes. Mostother acidsareweak electrolytes.2.The hydroxides(OH-) of the Group 1 metals are strongelectrolytes;Group 2 metals starting with Ca are moderate electrolytes. Most other basesincluding NH3are weak electrolytes.3.Most Salts (E.g. NaCl)are strongelectrolytes.4.The halides andcyanides (CN-) of “heavy metals”(E.g., Pb and Hg) are often weak electrolytes.5.Most organic compoundsare nonelectrolytes. Notable exceptions are organic acidsand bases, which are usually weak electrolytes.
