Question

solve
25. Which of the following solutions will have highest equivalent conductance?
a) 0.01 M NaCl b) 0.050 M NaCl c) 0.005 M NaCl d) 0.02 M NaCl

Answer 1

Answer:

0.01M nacl have high equivalent conductance

Answer 2

Option c) 0.005 M NaCl solution will have the highest equivalent conductance.

Explanation:

• The concept involved is that in the case of strong electrolytes, the molar conductivity decreases as the concentration of solution increases.
• On the other hand, for weak electrolytes, the molar conductivity increases as the concentration of solution decreases.
• The solution given in the options is the NaCl solution with varying concentrations.
• NaCl is a strong electrolyte. Thus as the concentration decreases, its molar conductivity increases.
• Therefore among the solutions given, the solution with 0.005 M has the highest equivalent conductance.
