Classify each of the following as either a weak electrolye, strong electrolye, or strong electrolye.

1) Co(OH)3

2)BaCl2

3) Ethanol, CH3CH2OH

I don\'t understand how to do this, so if you could explain how and why, that would be greatly appreciated!

Solution

Electrolytes are compunds which disassociate in water into ions to conduct electricity. If the compound has a high degree of disassocaition, then it is a strong electrolyte and vice versa.

Generally, strong acids and bases are strong electrolytes and weak acids and bases are weak electrolytes. Ehthanol would be a weak electrolye because it would not disassociate completely in water.

Mostly, the salts are strong electrolytes, and BaCl2 would be a strong electrolye.

Salts of complex ions are weak electrolyes, so CO(OH)3 would be a weak electrolyte.
