Which aqueous solution conducts electricity well?
A.NaCl(aq)
B.C₁₂H₂₂O₁₁(aq) (sucrose solution)
C.CH₃OH(aq) (methanol solution)
D.Pure H₂O
Explanation
Core Concept
Dissolved NaCl separates into mobile Na⁺ and Cl⁻ ions surrounded by water. These ions drift toward oppositely charged electrodes and complete the circuit. Conductivity tracks the concentration of mobile charges, which only the ionic solution supplies in quantity.
Correct Answer
ANaCl(aq)
