Variation in Conductivity Models
Variation in Conductivity Models Conductivity (κκ) and molar conductivity ( Λm\Lambda_mΛm) vary with concentration due to the interactions between ions in solution and the degree of ionization. Here’s how they typically change: Conductivity (κ\kappaκ): Increase in Concentration: Strong Electrolytes: Conductivity increases with concentration because more ions are present to conduct electricity. Weak Electrolytes: Initially, conductivity increases with concentration as more ions are produced through ionization. Higher Concentrations: For both strong and weak electrolytes, at higher concentrations, the increase in conductivity starts to level off or even decrease. This is due to ion pairing and increased ion interactions, which reduce the mobility of ions. Molar Conductivity (Λm\Lambda_mΛm): Molar conductivity is defined as the conductivity divided by the molar concentration (Λm=κ/C\Lambda_m = \kappa / CΛm=κ/C). Strong Electrolytes: Dilute Solutions: Molar conduc...
