This table presents the conductivity (k) and molar conductivity (Lambda_m) of potassium chloride
(KCl) solutions at 298.15 K (25°C).
Concentration (mol/L) Conductivity (S/m) Molar Conductivity (S·m²/mol)
0.0001 1.41 x 10^-3 141.0
0.001 1.29 x 10^-2 129.0
0.005 5.92 x 10^-2 118.4
0.01 1.11 x 10^-1 111.0
0.05 4.82 x 10^-1 96.4
0.1 8.53 x 10^-1 85.3
0.2 1.38 69.0
0.5 2.76 55.2
1.0 3.92 39.2
Notes:
- Conductivity (k) decreases with dilution due to fewer charge carriers.
- Molar conductivity (Lambda_m) increases with dilution as ion interactions decrease.
- The limiting molar conductivity (Lambda_m0) of KCl at infinite dilution is 149.86 S·m²/mol.
