Honors Chemistry - Electrolytes Worksheet

1. What is an electrolyte? What types of solutions are electrolytes?

What is a nonelectrolyte?

2. Define dissociation as it applies to ionic compounds that dissolve in water.

What does hydration mean?

3. Write equations for the dissociation of the following ionic compounds in water:

(a) LiCl

(b) BaCl2

(c) Al(C2H3O2)3

(d) (NH4)2CO3

(e) Al2(SO4)3

(f) KMnO4

(g) HNO3

4. What is the difference between a strong electrolyte and a weak electrolyte?

5. Nitrous acid, HNO2, is a weak acid. Write a chemical equation showing its reaction with water.

6. If a 0.5 M solution of MgI2 is totally dissociated into Mg2+ ions and I- ions, what is the molar concentration of each ion?

7. Explain what happens (and changes that occur) when a non-electrolyte such as sugar dissolves in water.
