  • A
    Specific conductance is the conductance of $1 \ cm^3$ of electrolyte solution.
  • B
    Specific conductance decreases while equivalent conductance increases on increasing dilution.
  • C
    The maximum value of equivalent conductance for a weak electrolyte cannot be determined by extrapolation of the curve between $\wedge_{eq}$ and $\sqrt{C}$.
