The conductivity of an electrolytic solution decreases on dilution due to:
The conductivity of an electrolytic solution decreases on dilution due to:
- A. decrease in number of ions per unit volume
- B. increase in ionic mobility of ions
- C. increase in percentage ionisation
- D. increase in number of ions per unit volume
Step-by-step solution
Conductivity of an electrolytic solution depends on the concentration of ions. Upon dilution, the concentration decreases, leading to fewer ions per unit volume, which reduces conductivity. Although dilution increases ionic mobility and percentage ionization (for weak electrolytes), these factors primarily affect molar conductivity, not the overall conductivity.
