Question

Which of the following has highest resistance during the passage of current.
1) 1N NaCl. 2) 0.1N NaCl
3) 2N NaCl. 4) 0.05 NaCl

Answer 1

Solution.

With increasing concentration of the electrolyte, reducing its conductivity and its resistance increases. Therefore, the 2N NaCl solution will have the greatest resistance.

Answer:

3) 2N NaCl
