At infinite dilution, each ion contributes independently to the total molar conductivity, regardless of the counter-ion present. Lambda_m_{infinity} = sum of cation and anion limiting conductivities: Lambda_m_{infinity} = nu+ * $lambda_{infinity}$(+) + nu- * $lambda_{infinity}$(-). Applications: (1) Finding Lambda_m_{infinity} for weak electrolytes: Lambda_m_{infinity}(CH3COOH) = Lambda_m_{infinity}(CH3COONa) + Lambda_m_{infinity}(HCl) - Lambda_m_{infinity}(NaCl). (2) Calculating degree of dissociation: alpha = \frac{Lambda_m}{Lambda_m_infinity}. (3) Determining Ka: combine alpha with Ostwald's dilution law. This is the most common Kohlrausch calculation in JEE.
