Which of the following solutions have highest resistance? — Electrochemistry Chemistry Question

💡 Solution & Explanation

Resistance is inversely proportional to specific conductance ($\kappa$). Specific conductance depends on the number of ions present per unit volume of the solution. The 0.05 N NaCl solution is the most dilute, having the lowest concentration of ions, the lowest specific conductance, and consequently the highest resistance. Therefore, correct answer is B.
