Conclusion:
More _____ions____________ in solution result in a __stronger___________ electrolyte.
Electrolyte – conducts electricity in solution

Strong electrolyte examples: soluble ionic compounds, strong acids (HCl, HBr, HI, HNO3,
H2SO4, & HClO4), and strong bases

Weak electrolyte examples: weak acids and weak bases
Nonelectrolyte – DOES NOT conduct electricity

Nonelectrolyte examples: molecular (covalent) compounds
Practice:
Name each substance then determine if it is a strong electrolyte, weak electrolyte, or
nonelectrolyte. (Refer to NMSI: Atoms, Molecules, & Ions packet for naming help)

2. LiClO3(aq)
3. C12H6O12(aq)
4. HF(aq)
5. HC2H3O2(aq)
