Which of the following electrolytic solutions has the least specific conductance?
Options
- A0.02 ~N
- B0.2 ~N
- C2 ~N
- D0.002 ~N
Correct answer
D. 0.002 ~N
Step-by-step solution
Specific conductance is defined as the conductance of one centimeter cube (cc) of the solution of an electrolyte. Upon dilution, the concentration of ions per cc decreases, so the specific conductance falls. Thus, specific conductance concentration of electrolytes, hence specific conductance is least for the solution of 0.002 ~N concentration.
