Specific and Molar Conductance: Specific Conductance: It is the reciprocal of Resistivity and is also known as “Conductivity“. It may also be defined as the conductance of one cm cube of the conductor. It is denoted by ‘κ‘ (kappa). Therefore, κ = 1/ρ = 1/R x l/a = C x l/a If l = 1 cm and a = 1 sq. cm, then κ = C Thus, specific conductivity of a solution is defined as “the conductance of a solution of 1 cm length and 1 sq. cm area of cross-section”. Units: Specific Conductance, κ = 1/ρ = 1/ohm cm … Continue reading What is Specific and Molar Conductance?
