Electrolytes, Ions and Solubility

• Almost all ionic compounds and a few molecular compounds are strong electrolytes.

• Several molecular compounds are weak conductors, most are non-conductors.

• Conductivity is directly related to the amount of ionization, i.e. ions in solution. Table salt, sodium chloride, is completely ionized:

NaCl(s) + H2O(l) ---> NaCl(aq) ---> 0.10M Na +(aq) + Cl -(aq) 0.00M 0.10M 0.10M
