Question

At infinite dilution equivalent conductance of NaI is greater in acetone medium than in

aqueous solution.​

Answer 1

It is due to the less density of acetone than aqueous solution.

Explanation:

• When dissociation of an ionic compound is complete this is called as infinite dilution.
• At this point each ion contributes with equivalence towards the conductance of the electrolyte.
• The value of conductance in an electrolytic solution is the sum of contribution made by each ion.
• The density of acetone is less than aqueous solution therefore ions move freely and rapidly.
• Thus at infinite dilution equivalent conductance of NaI is greater in acetone medium than in aqueous solution.​
