📊Student Analytics & Stats
Total Attempts: 5
Accuracy Rate: 60%
Step-by-Step Solution
The correct option is the number of ions per unit volume decreases. Conductivity is the conductance of ions present in unit volume of the solution. Upon dilution, the number of ions per unit volume of the solution decreases, leading to a decrease in conductivity.
