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 because they produce ions in solution. Urea is a non-electrolyte.
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
Step 1: An electrolyte is a substance that produces ions in aqueous solution and conducts electricity.
Step 2: Ionic compounds such as copper sulphate, silver nitrate and sodium chloride dissociate into ions in water. \[ NaCl \rightarrow Na^+ + Cl^- \] \[ AgNO_3 \rightarrow Ag^+ + NO_3^- \] \[ CuSO_4 \rightarrow Cu^{2+}+SO_4^{2-} \]
Step 3: Urea is a covalent compound. It dissolves in water but does not ionize significantly.
Step 4: Since urea does not produce ions in solution, its aqueous solution does not act as an electrolyte. \[ \boxed{\text{Urea}} \]
