What is the effect of dilution on the equivalent conductance of strong electrolyte?
Decrease on dilution
Remains unchanged
Increase on dilution
None of the above
C.
Increase on dilution
The equivalent conductance of strong electrolyte is increased by dilution, because its value is equal to the multiple of Kv and the volume of solution. By making dilution the volume of solution increases which also increase the value of equivalent conductivity.
