Specific conductance decreases while equivalent conductance increases on increasing dilution.

Vedclass · Answer

(NONE) $1$. Specific conductance (conductivity,$\kappa$) is defined as the conductance of $1 \ cm^3$ of electrolyte solution. This is a correct statement.$2$. On increasing dilution,the number of ions per unit volume decreases,so specific conductance $(\kappa)$ decreases. However,equivalent conductance $(\wedge_{eq})$ increases because the total volume containing one equivalent of electrolyte increases. This is a correct statement.$3$. For weak electrolytes,the curve between $\wedge_{eq}$ and $\sqrt{C}$ does not become linear at low concentrations,so the limiting equivalent conductance $(\wedge^0_{eq})$ cannot be determined by extrapolation. This is a correct statement.$4$. The conductivity of a metal is due to the mobility of electrons,and the conductivity of an electrolyte is due to the mobility of ions. This statement is also correct.Since all statements provided are scientifically correct,there is no incorrect statement among the options.
