Which of the following would act as a nonelectrolyte when dissolved in water? Select all that apply.
a. NH₄NO₃
b. NaCl
c. CH₃OH
d. K₂CrO₄
e. C₆H₁₂O₆

Solution

The answer is: (c) and (e)

CH₃OH and C₆H₁₂O₆ are molecular compounds and do not ionize in water. Thus they are nonelectrolytes.

All the others are soluble ionic compounds that will ionize in water and are thus electrolytes:

NH₄NO₃ => NH₄⁺ + NO₃^-

NaCl => Na⁺ + Cl^-

K₂CrO₄ => 2 K⁺ + CrO₄^2-
