An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to
Options
- Aincrease in ionic mobility of ions
- B100 % ionisation of electrolyte at normal dilution
- Cincrease in both, ie, number of ions and ionic mobility of ions
- Dincrease in number of ions
Correct answer
A. increase in ionic mobility of ions
Step-by-step solution
Key Idea _ eq = V = k 1000 normality . On dilution, the number of current carrying particles per cm ^3 decreases but the volume of solution increases. Consequently, the ionic mobility increases, which in turn increases the equivalent conductance of strong electrolyte.
