Question:
Aqueous solution of which of the following does not act as electrolyte?
Aqueous solution of which of the following does not act as electrolyte?
Show Hint
Electrolytes conduct electricity in aqueous solution because they produce ions. Urea is non-electrolyte because it does not ionize in water.
Updated On: May 7, 2026
- Urea
- Copper Sulphate
- Silver Nitrate
- Sodium Chloride
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
An electrolyte is a substance whose aqueous solution conducts electricity.
A solution conducts electricity only when ions are present.
Ionic compounds like sodium chloride, silver nitrate, and copper sulphate dissociate in water to produce ions.
For example:
\[
NaCl\rightarrow Na^+ + Cl^-.
\]
Similarly,
\[
AgNO_3
\]
and
\[
CuSO_4
\]
also produce ions in aqueous solution.
But urea is a covalent compound.
Urea dissolves in water but does not ionize into ions.
Therefore, aqueous solution of urea does not conduct electricity.
Hence, urea does not act as an electrolyte.
