Question 23 • EO Chemistry 7320B

Which is a characteristic of a nonelectrolyte?

Answer
A
It does not dissociate or ionize in water.
B
It partially dissociates or ionizes in water.
C
It conducts electricity poorly.
D
It conducts electricity extremely well.

Explanation

A nonelectrolyte does not dissociate into ions or ionize when dissolved in water. Since there are no mobile ions to carry charge, it does not conduct electricity. “Conducts electricity poorly” is not the defining characteristic, because a weak electrolyte conducts poorly but does form some ions.
