Which from following options is true when an electrolyte solution is diluted ?
Options
- Aboth and k increases
- Bboth and k decreases
- Cincreases and k decreases
- Ddecreases and k increases
Correct answer
C. increases and k decreases
Step-by-step solution
When an electrolyte solution is diluted, the volume of the solution increases, which leads to a decrease in the number of ions per unit volume. As a result, the specific conductivity ( k ) decreases. Molar conductivity ( ) is the conductance of the volume of solution containing one mole of the electrolyte. It is given by = k V . Upon dilution, the increase in volume ( V ) more than compensates for the decrease in specific conductivity ( k ). Additionally, for weak electrolytes, the degree of dissociation increases,
