Debye-Huckel's equation is given as ${\mathrm{\Lambda }}_{\mathrm{c}}={\mathrm{\Lambda }}_0-\mathrm{A}\sqrt{\mathrm{C}}$. It is useful to determine molar conductance at infinite dilution for all the following electrolytes except

It is applicable only to strong electrolytes;

It cannot be used to determine the molar conductance at infinite dilution of weak electrolytes;

Acetic acid is a weak electrolyte;
