The equivalent conductances of two strong electrolytes at infinite dilution in H2O (where ions move freely through a solution) at 25ºC are given below :
\(\Lambda_{\mathrm{CH}_{3} \mathrm{COONa}}^{\circ}\) = 91.0 S cm2/equiv.
\(\Lambda_{\mathrm{HCl}}^{\mathrm{o}}\) = 426.2 S cm2/equiv.
What additional information/quantity one needs to calculate Λº of an aqueous solution of acetic acid ?
\(\Lambda_{\mathrm{CH}_{3} \mathrm{COONa}}^{\circ}\) = 91.0 S cm2/equiv.
