The conductivity of 0.001M acetic acid is 4 times 10^-8 S//cm. Calculate the dissociation constant of acetic acid, if molar conductivity at infinite dilution for acetic acid is 390 S cm^2//mol.

Answer»

SOLUTION :`A_m=(K TIMES 1000)/m`
`=(4 times 10^-5 times 1000)/0.001`
`alpha=A_m/A_m^0=40/390=0.102`
